PureT (4UT46) Reducing Union Tee 1/4" OD x 1/4" OD x 3/8" OD Tube

The PureT 4UT46 Reducing Union Tee connects tubing of different diameters in configurations where two 1/4" OD lines merge into a single 3/8" OD output. This push-to-connect fitting provides secure, leak-free connections in reverse osmosis systems, water filtration setups, and distribution manifolds without requiring tools or thread sealant.

Technical Details

Model Number 4UT46
Manufacturer PureT
Fitting Type Reducing Union Tee
Connection Method Push-to-Connect
Port 1 & 2 Size 1/4" OD Tube
Port 3 Size 3/8" OD Tube
Material FDA-Compliant Plastic
Application RO Systems, Water Filtration Lines
INSTALLATION & USE

Connection Procedure

  1. Cut tubing ends squarely with a tube cutter to ensure clean, perpendicular cuts with no deformation.
  2. Push each tube fully into its corresponding port until it seats against the internal stop. You should feel resistance when fully inserted.
  3. Tug gently on each tube to confirm the collet has gripped properly. The tube should not pull free with moderate force.
  4. Pressurize the system slowly and inspect all three connections for leaks before returning to full operating pressure.
COMPATIBILITY

System Integration

The PureT 4UT46 works with standard 1/4" and 3/8" OD tubing used in residential and light commercial reverse osmosis systems. This reducing tee is commonly used to combine two filtration stages into a single feed line, create distribution points from smaller lines to larger delivery tubes, or branch permeate flows in multi-tap configurations. Compatible with polyethylene, nylon, and LLDPE tubing meeting NSF standards for potable water contact.

🔧 Pro Tip: Before disassembling a push-to-connect fitting, depressurize the system completely and press the collet release ring while pulling the tube. Forcing tube removal without releasing the collet can damage the internal grip mechanism and compromise the seal on reinstallation.
