About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Dual-Section Right-Angle Flow Rectangular Manifolds

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Manifolds are also known as headers. They have mounting holes, so you can mount from the top or side. Manifolds are anodized aluminum, which is lightweight with good corrosion and wear resistance.

Use a plug (sold separately) to close off any unused inlets and outlets.

Color-Coded Irregular Hex Manifolds

Use these manifolds with injection molding equipment to circulate hot and cold water through your line. They have a compact body with outlets on five sides, so you can run multiple lines from one supply source. Manifolds have mounting holes that let you mount from the top. They are anodized aluminum, which is lightweight with good corrosion and wear resistance.

Dual-section manifolds have both a red side for hot water and a blue side for cold water.

Use a plug (sold separately) to close off any unused inlets and outlets.
