Typical Applications
Used where a 1/2 in. air-brake line must turn 90 degrees into a 3/8 in. ported valve, gladhand, or reservoir on trucks and trailers. The swivel feature is valuable in tight chassis spaces, letting installers orient the tube leg without back-turning the thread or risking a leak path.

It accepts 1/2 in. OD D.O.T.-rated air-brake tubing.
What hex size is needed?
The thread end uses an 11/16 in. hex.
Is sealant required on the NPTF thread?
NPTF can self-seal, but PTFE tape or air-rated pipe dope is recommended.
