How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

The grooved ends on these fittings connect to pipe with a clamp to easily install piping systems. Since there’s no heat or threading required, they provide quick access to a pipe line for routine maintenance. Fittings are also known as Victaulic fittings. They are for use in noncorrosive applications.

Drain, Waste, and Vent Iron Pipe Fittings

Use these fittings in gravity-flow applications both above and below ground. They are also known as no-hub pipe fittings and soil pipe fittings. To connect, place the end of the fitting against your pipe or another fitting and connect with a low-pressure clamp-on connector (sold separately). The clamp-on connector is also known as a no-hub coupling. Fittings are for use in noncorrosive environments.

Easy-Access CPVC Pipe Fittings 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

Also known as Victaulic fittings, these have grooved ends that connect to pipe with a clamp, so you can access your chemical process line for routine maintenance. Fittings are CPVC, which has excellent chemical resistance to withstand a variety of salt solutions, acids, and other harsh substances. They are comparable to Corzan. Fittings meet ASTM D1784 specifications and testing requirements for material quality.

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

Vacuum Fittings for Steel Tubing

For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
Temperature Range: -10° to 180° F
Tubing: Galvanized Steel: Use with steel, galvanized steel
Steel: Use with steel

Use these fittings to create an air vacuum system without the hassle of brazing and welding. Insert two fittings into a clamp (sold separately) and tighten to form a secure seal.

Galvanized steel fittings have fair corrosion resistance. Fittings without a finish should only be used in noncorrosive environments.
