Oil Only Absorbent Pads

Hydrophobic pads that pick up the oil and leave the water behind

In any application where oil and water mix — a flooded engine bay, a rain-exposed maintenance area, a boat bilge, a stormwater outfall — universal absorbent pads work against you. They saturate with water before they reach the oil. Oil-only pads solve that with a hydrophobic polypropylene fiber that repels water and only takes up hydrocarbons. Drop one in a puddle and it'll float, dry on the bottom, until oil contacts it.

Our white 15" x 20" oil-only pads come in two weight classes. Both are dimpled, both perforated for tear-off use, both made from meltblown polypropylene. The white color is industry standard for oil-only — it lets a maintenance team see at a glance what's been absorbed and when a pad needs to come out of service.

2mm standard 200-pack: Routine fuel drips, transfer point cleanup, light marine work, daily wipe-down on outdoor equipment.

3mm heavy 100-pack: Sustained leaks, response kits, drag-and-wring use, applications where you want fewer pad changes per event.

Want to test absorbency on your specific fluid before a bulk PO? Order the free absorbent pad sample box and run it on diesel, hydraulic oil, motor oil, or whatever your team is dealing with.

Where oil-only pads earn their keep

Oil-only sorbents are the right product for marine bilges and dock decks, stormwater drains and outfalls, outdoor fuel storage and transfer points, tanker truck loading, oil-water separator service, and any indoor process where you specifically need to keep water out of the absorbent. For continuous coverage of those applications, pair with oil-only absorbent mat rolls or oil-only absorbent booms. For marine engine compartments specifically, the 5" x 18" bilge oil absorber is purpose-built for the space and fits inside most bilges without modification.

Choosing oil-only absorbent pads for marine, stormwater, and outdoor use

Hydrophobic vs. universal: what changes inside the pad

Fiber chemistry is the only real difference between an oil-only pad and a universal pad. Universal pads have a surface treatment that lets water enter the fiber matrix; oil-only pads don't. That means oil-only sorbents sit on a wet deck or a rain-soaked floor and stay buoyant indefinitely — they only pick up petroleum products, vegetable oils, transmission fluid, hydraulic fluid, fuel, and other hydrocarbons. In a USCG-regulated environment, oil-only is the default answer: 33 CFR 154 and 33 CFR 155 contemplate sorbents that won't sink or saturate with seawater. The same logic applies to any EPA SPCC plan covering an outdoor or partially exposed area where stormwater contact is likely (40 CFR Part 112).

Weight class selection

The 2mm standard pad is the workhorse for everyday use — drip pans under fuel dispensers, daily wipe-downs on outdoor equipment, light kit replenishment. Lower cost per pad, faster wear-through. The 3mm heavy pad roughly doubles per-pad capacity. Choose it when the pad needs to stay deployed for hours, when you're stockpiling for response kits that may sit for weeks, when the work involves dragging or wringing, or when your team simply prefers fewer pad changes during a single event.

Where oil-only pads belong

Oil-only sorbents are the right pick for:

•       Marine bilges, engine compartments, and dock decks. Pads stay buoyant in standing water and only absorb the fuel sheen or oil weep.

•       Stormwater drains, ditches, and outfalls. Place pads upstream of grates to intercept hydrocarbons before they enter the system.

•       Outdoor fuel storage and transfer points. Drip control under spigots, pumps, and quick-disconnect fittings without absorbing rainwater.

•       Tanker truck loading and unloading stations. Stage pads in catch basins and along hose runs.

•       Coolant-water separation in machining. Oil-only pads recover float oil from coolant sumps without removing the coolant itself.

•       Oil-water separators. Used as replacement sorbent media in OWS service.

•       Open-air maintenance bays and rain-exposed shops. The right call for any indoor area that gets wet from outside.

What oil-only pads won't do

They won't pick up water-based fluids. That sounds obvious, but it matters indoors: if you stock only oil-only in a CNC shop running water-soluble coolant, the coolant puddles will sit there untouched. Indoor industrial maintenance with mixed fluids is the use case for universal pads or universal mat rolls, not oil-only. They also aren't optimized for aggressive chemical service — for concentrated acids or bases, switch to chemical hazmat pads.

Sizing the absorbent supply

The 2mm standard 200-pack absorbs approximately 38 gallons of oil per box (~0.19 gal/pad). The 3mm heavy 100-pack carries similar total volume per box because each pad holds roughly double. In real conditions, plan on 60–75% of stated capacity. For a marine bilge with a slow weep from an engine, two or three pads typically last a week. For a fueling station that handles 50+ gallon dispenses, stage at least one 100-pack of heavy weight plus absorbent booms for any larger release.

Disposal and waste classification

Oil-saturated pads are universal waste in some jurisdictions and hazardous waste in others — it depends on what's in the oil. A pad saturated with used motor oil triggers different rules than one saturated with diesel fuel, and waste oil with detected halogens often classifies differently again. Consult your facility's environmental compliance officer and the Spill Control Resource Center for documentation practices.

Bulk orders and combined kits

We package oil-only pads alongside booms and disposal supplies as configured marine and outdoor spill kits. Call 888-774-5528 or submit a quote request with your fluid type, expected volume, and site count for kit-level pricing.

Oil Only Absorbent Pads — Frequently Asked Questions

What is the difference between oil-only and universal absorbent pads?

Oil-only pads are hydrophobic — they repel water and absorb only hydrocarbons (oil, fuel, hydraulic fluid, motor oil, transmission fluid). Universal pads take up both water and oil. Choose oil-only for marine, stormwater, outdoor, or any application where water contact would saturate the pad before the oil arrives. Choose universal pads for indoor maintenance where the spill could be either.

Will oil-only pads work in rain or standing water?

Yes. The polypropylene fiber is hydrophobic, so the pad floats on water and stays dry on the bottom until oil contacts it. That's the entire point of the product: it picks up the hydrocarbon layer without absorbing the water beneath. This is what makes them appropriate for boat bilges, stormwater drains, and outdoor fuel transfer.

How much oil does one pad absorb?

The 2mm standard 15"x20" pad holds approximately 0.19 gallons each (~38 gallons per 200-pack box). The 3mm heavy weight in the same dimensions holds roughly double per pad. Stated capacity is laboratory maximum; in real conditions plan on 60–75% of that based on viscosity, temperature, and handling.

Can I use oil-only pads in a U.S. Coast Guard regulated facility?

Yes. Oil-only sorbents are the standard product class contemplated by 33 CFR 154 and 33 CFR 155 for facility response plans involving petroleum on water. The white color is the industry convention for oil-only and is recognized in most marine spill response training programs.

Are these pads compatible with diesel, gasoline, motor oil, and hydraulic fluid?

Yes — all four are standard hydrocarbons that oil-only polypropylene pads absorb readily. They also pick up vegetable oils, transmission fluid, brake fluid, mineral spirits, kerosene, and most cutting oils. For chemical service involving acids, bases, or aggressive solvents, switch to chemical hazmat pads.

What are oil-only absorbent pads made of?

Meltblown polypropylene fiber, untreated so the natural oleophilic (oil-loving) and hydrophobic properties of polypropylene work as designed. The meltblown process produces a fine, lofted fiber structure that traps liquid hydrocarbons by capillary action while resisting water uptake.

Do you offer free samples?

Yes — the Spill Ready absorbent sample box ships free and includes oil-only and universal pad samples. It's the simplest way to verify performance on your specific fluid before a bulk order.

How are used oil-saturated pads disposed of?

The pad itself is non-hazardous polypropylene. Once saturated with oil, the pad inherits the hazard profile of the absorbed product. Used motor oil, diesel, and similar standard petroleum products typically follow universal-waste or non-hazardous industrial waste rules depending on jurisdiction. Confirm with your environmental compliance officer or licensed waste hauler before disposal.

Do you offer bulk pricing for fleet or facility-wide orders?

Yes. Volume pricing applies on multi-box orders and improves when paired with oil-only mat rolls, booms, or full marine response kits. Call 888-774-5528 or use the contact page with quantities and SKUs.

How fast do orders ship?

Stocked items ship same-day from the Solon, Ohio warehouse on orders placed before the daily cutoff. Larger pallet orders ship LTL freight with carrier confirmation on quote. See the shipping page for current free-shipping thresholds and transit estimates.
