Radiused Tank Adapters

Unleash the performance of your poly tank with fittings up to 24”. Until now, the functional capabilities of polyethylene tanks have been limited due to a relatively small selection of commercially available fittings and accessories which are further limited as tank diameters get smaller. Today, CRP Tank Specialties, Inc. brings to market a wide range of high performance 6”-24” tank adapters. Our fiberglass fittings and manways have been granted U.S. Patent no. 9,464,745.

Radiused Side Manways

When it comes to tank cleanout, inspection, maintenance, and safety, our side manways bring a whole new world of operational performance to poly tanks. The remarkable performance track record of our side manways is testament to the importance of stress elimination on both the tank and the fitting. And because we radius the mounting saddle to your tank, a 24” manway on the side of a 48” diameter tank is no problem. These are available in fiberglass and stainless steel as standard. We have been granted U.S. Patent no. 9,464,745 for the fiberglass version of our side manways.
