New Pig Mildew-Resistant Absorbent Sock (PIG105-BL) — Water-Absorbing, 3 in x 4 ft, 12-Pack

New Pig Mildew-Resistant Absorbent Sock overview

The New Pig Mildew-Resistant Absorbent Sock (PIG105-BL) comes 12 to a box, each sock 3 in x 4 ft, and does the containment job: surround, ring or dam a water spill and steer it away from drains and doorways. Each sock absorbs up to about a gallon, and because the skin and filler are 100% polypropylene — not cellulose — it resists mildew, which is why it holds up in damp, long-placement spots where an ordinary sock would eventually mold. The polypropylene skin also resists tearing, holds liquid in when saturated, and reduces loose dust. See our best spill kits guide and the spill control collection.

Two things worth reading right. First, chemistry: this is a water sorbent, so it isn't the sock for oil or aggressive chemicals — for oil and fuel choose an oil-only boom that repels water, and for a rigid dam use the spill barrier dike. Second, use it as a system: socks contain while pads finish — ring the leak with the sock, then wipe with the water mat pads, and keep a bucket kit like the KIT21 nearby for a grab-and-go station. New Pig rates the sock to be squeezed or air-dried and reused about one to three times; keep it out of direct sunlight, since UV degrades polypropylene.

Where it fits

This is the water-containment sock for ringing leaks under HVAC units, water heaters, coolers, sinks and machines; damming water at doorways in wet weather; and laying a barrier along a wall or the edge of a work zone. Its mildew resistance makes it a good pick where a sock sits in place for a long time in a damp area. Where it's not the tool is an oil or fuel leak (use an oil-only boom) or an aggressive chemical (use a HazMat sock or kit) — and to protect a drain, add a drain cover. Keep protection nearby: our chemical-resistant gloves guide covers hand protection, and a first-aid kit should be close.

Frequently asked questions

What does the New Pig Mildew-Resistant Absorbent Sock absorb?

It's a water-absorbing sock, so it takes up water and water-based liquids and holds them even when saturated. It isn't an oil-only or universal sock, so it isn't the pick for oil, fuel or solvent spills.

What makes it mildew-resistant?

Its skin and filler are 100% polypropylene rather than cellulose, so the sock resists mildew growth. That's why it holds up in damp, long-placement spots — around HVAC units, coolers and entryways — where a cellulose sock would eventually mildew.

How much does each sock hold, and how many come in a box?

Each sock absorbs up to about a gallon of water, and they come 12 to a box. The 3 in x 4 ft length lets you lay a continuous barrier or ring a leak with several socks end to end.

How is a sock different from an absorbent pad?

A sock is a flexible tube you use to surround, contain or dam a spill and steer it away from drains and doorways; a flat pad covers an area to soak up or wipe a spill. Many cleanups use socks to contain and pads to finish.

Can I reuse the sock?

Yes, a few times. New Pig rates it to be squeezed out or laid flat to air-dry and reused about one to three times. Keep it out of direct sunlight, because UV exposure degrades the polypropylene over time.

Will it absorb oil or fuel?

No — it's tuned for water and water-based liquids. For oil and fuel, especially around water or outdoors, use an oil-only boom or sock that repels water; for mixed oil-and-water spills use a universal sock.

What is the sock made of, and does it shed dust?

The skin and filler are 100% polypropylene. The skin resists tearing, holds liquid in even when the sock is saturated, and reduces the loose dust you get with clay or some other fillers.

Is this a complete spill kit?

No — it's a containment component (a refill), not a kit with a container, pads, gloves and disposal bags. Pair socks with pads and a bucket kit to build a station, or drop them into a kit you already own.

Does the sock neutralize what it absorbs?

No. A sorbent sock holds liquid but does not neutralize it. For acids, bases or aggressive chemicals you need a HazMat or neutralizing product — check the liquid's safety data sheet first.

Where are these socks typically used?

Ringing leaks under HVAC units, water heaters, coolers, sinks and machines; damming water at doorways in wet weather; and laying a barrier along a wall or the edge of a work area. The mildew resistance suits long-term, damp placements.

What color is this sock, and are there other options?

This is the blue PIG105-BL. New Pig offers the same sock in black or blue to blend with surroundings, or yellow for high visibility where you want the barrier to stand out.

How do I dispose of a used sock?

For clean water, a used sock is generally ordinary waste, but if it took up anything else it carries that liquid's hazard — dispose of it per your local, state and federal rules and the liquid's safety data sheet.

Reviewed by Steven Eaton, WC Safety. Specifications reflect New Pig's published data for the PIG105-BL mildew-resistant absorbent sock; it is a water sorbent (not oil or chemical) and is rated for limited air-dry reuse — match the sock and your PPE to the specific liquid via its safety data sheet.
