NP69-6-6
This is a 90-degree push-to-connect air brake fitting, commonly called a push-lock or push-on elbow. It connects 3/8-inch outside diameter nylon air brake tubing to a 3/8-inch male NPT port, allowing quick, tool-free installation. The swivel elbow design helps route air lines in tight spaces on trucks and trailers. Typically replaced when a fitting is cracked, leaking, or when reconfiguring air lines.
Fits any heavy-duty truck or trailer air brake system using 3/8" SAE J844 nylon tubing and a 3/8" NPT female port. Listed for common trailer types but is not vehicle-specific.
