Male Adapter - NPTF Thread

John Guest male adapter with NPTF thread

Fitting to connect a tube line to an NPTF threaded connection. Current variants combine 3/8" or 1/2" tube with 1/4, 3/8 or 1/2 NPTF threads.

How to choose

Check the tube’s outside diameter and the equipment’s NPTF thread. The nominal thread size is not the same as the outside diameter measured with calipers, so it is advisable to identify the standard before purchasing.

Installation

With the system unpressurized, first assemble the threaded part in line and prepare the tube with a square cut. Insert the tube fully and perform a leak test.

Applications

Suitable for transitions between dispensing tubing and equipment or accessories with NPTF.
