The 3/8" stem elbow is used to alter the exit angle of lines from other John Guest fittings by 90° .
Stem elbows reduce stress at joins which can result in gas or fluid leaks as a result of lateral line pressure.
It is the fitting of choice for Micromatic Secondary Regulators to achieve a tidy and leak free Gas System using HD 3/8"John Guest Gas Line. It comes with a free locking collet.
The "3/8" male end fits neatly and securely into any other 3/8" John Guest Speedfit® fitting.
