How to Measure Threaded Pipe Size

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.

Low-Pressure Galvanized Iron and Steel Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection. Fittings are made of galvanized iron or steel, which have fair corrosion resistance. Also known as Pressure Class 125 or 150 fittings, they are for use in low-pressure applications.

NPTF (Dryseal) threads are compatible with NPT threads.

Miniature Medium-Pressure Stainless Steel Threaded Pipe Fittings

When space is at a premium choose these compact fittings. Though small in size, they have the strength to handle medium-pressure applications. Fittings are stainless steel for very good corrosion resistance.

Metric, BSPP, and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. Made from fluoroelastomer, these gaskets resist chemicals, including benzene, butyl alcohol, and ethylene glycol. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Plastic Pipe Fittings for Oil

Made of corrosion-resistant plastic, these fittings won’t deteriorate when used in oil applications. They also have high strength and impact resistance. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

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