1/2″ Air Brake Push-In Union Elbow
$24.00
1/2″ push-in union elbow connects two 1/2″ OD nylon air lines through a fixed 90-degree turn in compatible truck and trailer air brake systems, while reusable collets let each tube release for servicing without a threaded port.
Part number DQ65DOT08.
Description
Overview
The 1/2-inch air brake union elbow joins two 1/2-inch OD nylon air lines through a fixed 90-degree turn. Both ends use push-to-connect collets, so the tube size stays unchanged while the line changes direction in a compact fitting. This version suits tube-to-tube routing because neither port is threaded.
Features
- Two 1/2-inch push-to-connect tube ports
- Fixed 90-degree union elbow configuration
- Reusable fitting with depress-to-release collets
- Brass construction for air brake service
Specifications and Materials
Configuration: imperial DOT push-to-connect union elbow. Tube size: 1/2-inch OD at both ends. The body connects equal-size nylon tube through a 90-degree bend, while the collets retain each tube without separate compression nuts.
Part number: DQ65DOT08.
See the manufacturer union elbow technical page
Compatibility and Fitment
Confirm both lines are 1/2-inch OD before ordering. The main mismatch risk is choosing a male elbow that looks similar but carries a threaded connection on one side. This union elbow instead accepts tube at both ports. Cut each tube square, remove damaged or flattened sections, then push the tube fully home into each collet.

Compliance and Safety
This DOT push-to-connect fitting family is approved to meet ADR 38/05, FMVSS 571.106, SAE J2494/3 and SAE J1131. Depressurise the circuit before disconnecting a line. After assembly, restore pressure gradually and leak-check both joints. Inspect the tube ends because scoring, angled cuts or incorrect tube size can affect sealing.
Trailer Applications
The 1/2-inch air brake union elbow suits compatible truck and trailer air brake, air suspension and auxiliary pneumatic circuits where a 1/2-inch line needs a right-angle change without reducing tube size. Its equal-port layout is useful around chassis rails, valve groups and other areas where a straight union would create an awkward tube path.
