Product Details

The AquaLock 3514-1008 is a push-to-connect plastic reducing stem designed to transition from 1/2 inch CTS to 3/8 inch CTS tubing with no tools required. Manufactured from durable off-white polysulfone with an EPDM O-ring, this fitting delivers a reliable, zero-leak connection for residential and commercial plumbing applications.

Unlike traditional barb fittings, the AquaLock stem connects tubing on the outside, which maintains greater flow capacity through the line. A unique O-ring guide feature ensures a secure, leak-free seal every time, and once connected, the tubing retains the ability to swivel—making this fitting well-suited for vibrating or dynamic plumbing installations.
