Parker PP6EU6 Push-to-connect Union Fitting 3/8 in Od

Product Description

The PARKER PP6EU6 is a push-to-connect union tube fitting designed for tube-to-tube connections in fluid handling and pneumatic systems. It accepts 3/8 inch OD tubing on both ends and creates a leak-resistant connection without tools — tubing inserts and locks in place instantly. Constructed from polypropylene with a tan color designation, this fitting is rated to 150 psi and suits applications where a lightweight, corrosion-resistant union is needed. Plumbers, HVAC technicians, and industrial pipe fitters use this style of fitting for quick-connect runs in water, air, and compatible fluid lines.

This fitting is suited for residential and light commercial fluid distribution systems, pneumatic lines, and water treatment or filtration plumbing where a simple inline union is required. Its push-to-connect design is particularly practical in tight spaces or panel-mounted installations where threading or soldering is not feasible. The polypropylene body resists corrosion and chemical attack in typical water and air service environments.

Installation Notes

Installation is performed by plumbers or HVAC technicians. Before installing or replacing this fitting, shut off and depressurize the supply line completely. Ensure tubing ends are cut square and deburred for a proper seal — angled or rough cuts can cause leaks at the collet. To remove tubing, depress the release collar evenly while pulling the tube straight out; do not twist or pry.
