About Pipe and Fittings

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

Easy-Access CPVC Pipe Flanges for Chemicals

For Use With: Acetic Acid (10%), Calcium Chloride, Deionized Water, Hydrochloric Acid, Phosphoric Acid, Salt Water, Sodium Hydroxide, Sulfuric Acid (80%), Water
Temperature Range: 32° to 200° F
Specifications Met: ASTM D1784
Pipe Nipples and Pipe: Use Schedule 80 CPVC Plastic

The grooved ends on these flanges connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. They are also known as Victaulic flanges. Bolt two same-size flanges together with a gasket (sold separately). Flanges are CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are comparable to Corzan. Flanges meet ASTM D1784 specifications and testing requirements for material quality.

Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

Clamps for Vacuum Fittings for Steel Tubing

Use these clamps to connect vacuum tube fittings. Insert two fittings into a clamp and tighten to form a secure seal.

Bolt Clamps

For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
Temperature Range: Neoprene Rubber Gaskets: -20° to 190° F
Silicone Rubber Gaskets: -100° to 500° F
Tubing: Use with steel

Bolt clamps have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully-grounded system. They have fair corrosion resistance.
