Reducing Union Tee 3/8 x 1/4 x 3/8 Air Fitting
$20.00
This brass reducing union tee connects two 3/8″ nylon air lines through the straight run and adds a 1/4″ compression branch. It includes the matching nuts, olives and tube inserts for all three connections.
Part number 36-014R-060604.
Description
Overview
The 3/8 x 1/4 reducing union tee divides a 3/8″ nylon air line through a smaller 1/4″ centre branch while maintaining the 3/8″ straight-through run. Its three compression connections suit pneumatic repairs where the branch requires a lower tube size without introducing a threaded port.
Features
- Two 3/8″ compression ends form the straight-through connection
- One 1/4″ compression end creates the reduced centre branch
- Brass tee body for imperial nylon air brake tube
- Includes the matching compression nuts, olives and tube inserts
Specifications and Materials
This reducing union tee connects 3/8″ tube at both ends of the run and 1/4″ tube at the centre branch. The supplied compression hardware supports and seals all three tube connections without requiring flared tube ends. Part number: 36-014R-060604.

Compatibility and Fitment
Confirm the tube outside diameter at every port before ordering. The two opposing connections require 3/8″ imperial nylon tube, while the centre branch requires 1/4″ tube. Do not confuse this fitting with an equal 3/8″ tee, a push-in tee or a tee with a threaded branch.

Compliance and Safety
Cut each nylon tube square and remove burrs before assembly. Check that the correct insert supports each tube, tighten the nuts evenly and pressure-test all three joints. Replace scored tube, distorted olives or damaged inserts rather than relying on overtightening to stop a leak.
