Other Straight-Thread Pipe Adapters

Plastic Pipe and Pipe Fittings

Plastic Pipe and Pipe Fittings

Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings. They are typically for low- to medium-pressure applications up to 1,000 psi.

Junction Blocks

Junction Blocks

Use junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.

Manifolds

Also known as headers, manifolds allow you to distribute air or fluid to multiple locations from a single supply source.

Tubing and Tube Fittings

Hose Fittings

Connect these fittings to lengths of hose. Hose fittings are typically used in high-flow, suction, and hydraulic applications.
