Description

Overview

The 12mm x 3/8 NPT swivel male elbow connects 12mm metric nylon tube to a female 3/8 NPT port and turns the line through 90 degrees. Its swivel base lets the installer tighten the threaded connection first, then aim the tube away from nearby hardware.

Features

• Push-in collet accepts 12mm outside-diameter air brake tube.
• Swivel body changes direction without twisting the connected tube.
• Brass construction carries the threaded base and push-to-connect joint.
• Pre-applied thread sealant covers the 3/8 NPT male connection.

Specifications and Materials

The fitting uses CA360 and CA377 brass with an NBR tube-sealing O-ring. It carries a maximum working pressure of 150 PSI and operates from -40°C to 104°C. The push-in end suits compatible SAE J844 nylon air brake tubing, while Loctite 516 seals the tapered male thread.

Part number: 88-M005S-12N06.

The manufacturer technical specifications cover the fitting size and operating limits.

Compatibility and Fitment

Measure the tube across its outside diameter and confirm the receiving port uses a 3/8 NPT female thread. The main ordering risk is confusing this fitting with 3/8 BSP, because the nominal size appears similar but the thread pitch and form differ. Also check that the 12mm x 3/8 NPT swivel male elbow can rotate freely into its final position.

Cut the tube square, remove burrs and push it fully through the collet to the internal stop. Then pull back lightly to confirm the gripping teeth have engaged.

Compliance and Safety

Depressurise the circuit before installation or removal. Inspect the tube surface, collet and threaded port for scoring, contamination or damage. After assembly, restore pressure gradually and leak-test both joints before returning the trailer to service.

Trailer Applications

Workshops fit this elbow where a 12mm air line must leave a 3/8 NPT port at a right angle. Typical positions include air brake valves, suspension controls, reservoir connections and auxiliary pneumatic manifolds where a straight fitting would force an unsuitable bend.
