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.

Breakaway Hose Couplings for Chemicals and Petroleum
Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated. Attach one end to your hose and the other to a supply pipe or a second hose.
Aluminum couplings are lightweight and have good corrosion resistance.
316 stainless steel couplings have excellent corrosion resistance.
3/4 NPT and 3/4 BSPP couplings can be reconnected without replacement parts.
1 NPT couplings cannot be reconnected.
2 NPT and 3 NPT couplings have bolts designed to break before your hose does. They can be repaired with replacement bolt kits and replacement seal kits (both sold separately).
