These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

With thinner walls than Schedule 40 fittings, these are lighter in weight and have more space on the inside for high-flow applications, such as underground gravity-flow sewer and storm drainage lines. They are also known as SDR 35 fittings.

Use these rotating joints to transfer high-temperature materials from your supply line.

Joints are for one-way flow and are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.

Joints are for two-way flow and are stainless steel for excellent resistance to corrosion caused by fluid flowing through them.

Joints are for two-way flow and are brass for good corrosion resistance.

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings.

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.
