Mobile Plastic Tanks

Custom Holding Tanks for Mobile Applications 

Mobile Plastic Tanks ManufacturerWe fabricate mobile plastic tanks to virtually any shape or size!

Our custom holding tanks are designed to take full advantage of every cubic inch of space and floor plan. Angles, radii, cut outs, notches, are never a problem.

Send us your sketch and you'll typically have a new custom tank in 2 weeks or less!

Typical applications include:

RVs Micro Homes
Campers Restroom Trailers
Trailers Office Trailers
Boats & Yachts Special Event Trailers

Flexible Vehicle Connectivity

We make connectivity to your vehicle flexible by machining threads directly into tank walls for low profile plumbing installations.

We can also provide welded-on threaded fittings or barbed connectors.

Reduced Sloshing & Complete Emptying

Unlike a molded tank, we can install internal supports and baffles to strengthen the welded holding tank and reduce sloshing.

We can also install castellated pick-ups and truncated baffles to allow complete emptying.

Greater Protection

Welded plastic holding tanks are far superior to molded holding tanks due to consistent wall thickness and overall heavier construction, which makes road hazard penetration less likely.

Highest Accuracy & Quality

plastic holding tanks manufacturerWe cut all plastic holding tank components with the latest in CNC equipment, and use only Virgin U.S. material to ensure the absolute highest quality.

This accuracy and quality is repeated on every plastic holding tank for consistent operation and reliable function.

Highest Standards

It’s important to note that we weld our plastic tanks to the more strict German DVS welding standards.

This specification is used to measure the integrity of commercial chemical and acid tanks, so you can be assured of long-lasting integrity for this critical component.

We boast the best welds in the industry and are eager to prove it to you. Get your free weld sample!
