Fitting FAQs

HDPE stands for high density polyethylene which is a thermoplastic derived from petroleum. HDPE is a tough but flexible plastic that is used to manufacture a wide range of products.

HDPE Fittings connect HDPE Corrugated Drainage Pipe, also known as Culvert Pipe. Single Wall Fittings are compatible with Single Wall HDPE Pipe and Double Wall Fittings are compatible with Double Wall Pipe. Injection Molded Fittings are compatible with Double Wall Pipe, but some customers prefer these fittings even for their Single Wall Pipe because the single injection mold is stronger.

A MarMac coupler connect HDPE and PVC Pipe. Inquire with our sales team if you require a MarMac coupler.

You need a Band Coupler (also known as a Split Coupler) for every opening when connecting pipe and fittings. For example, if you are connect a stick of HDPE Double Wall Solid Pipe to a HDPE Wye, you need three Band Couplers for that connection. To connect two sticks of Double Wall Solid HDPE Pipe, you need just one Band Coupler.
