501 Series Standard Tee With Groove Transition | HDPE × Grooved Steel
501 Series Standard Tee With Groove Transition | HDPE × Grooved Steel — Product Overview
The Series 501 Standard Tee with Groove Transition from Poly-Cam offers a reliable and high-performance mechanical connection between HDPE pipe and grooved steel systems. Designed for use in municipal, industrial, and mechanical piping applications, this transition fitting ensures a permanent, leak-resistant seal—delivering dependable performance even under pressure and temperature fluctuations.
The fitting features hydraulically compressed, high-quality polyethylene or copolymer material cold-pressed into a grooved steel coupling. The internal multi-barb design maximizes sealing force as internal pressure rises, while also maintaining secure engagement under zero pressure. With grooves cut to standard specifications and sizes ranging from 1" to 8" IPS, the Series 501 is engineered for strength, durability, and long-term service.
