Product Description

The SPEARS Expansion Joint (MPN EJ21-015CSR) is a threaded CPVC expansion joint with an EPDM bulb, designed for 1 1/2 in pipe size and a 7.75 in overall length. It supports a maximum operating pressure of 150 psi, providing a reliable solution for thermal expansion in CPVC piping systems.

Frequently Asked Questions

What is a SPEARS CPVC expansion joint used for?

A SPEARS CPVC expansion joint absorbs thermal expansion and contraction in CPVC piping systems, preventing stress on joints and fittings. It is commonly used in industrial plumbing, chemical processing, and HVAC applications where temperature fluctuations occur.

What are the specifications of the SPEARS EJ21-015CSR expansion joint?

The SPEARS EJ21-015CSR is a threaded CPVC expansion joint with an EPDM bulb, designed for 1 1/2 in pipe size. It has a 7.75 in overall length and a maximum operating pressure of 150 psi, making it suitable for moderate-pressure thermal expansion applications.

Where to buy SPEARS expansion joints worldwide?

3G Electric supplies SPEARS expansion joints worldwide, handling full logistics and customs clearance. As a global industrial solutions provider, we source and deliver genuine SPEARS parts like the EJ21-015CSR to support thermal expansion needs in CPVC systems across industries.

How to install a threaded CPVC expansion joint?

Install a threaded CPVC expansion joint by applying PTFE tape or pipe dope to male threads, hand-tightening, then using a wrench for a snug fit—avoid overtightening to prevent cracking. Ensure the joint is aligned with the pipe run to allow free axial movement for thermal expansion.

Used in

Common applications for SPEARS
Chemical processing — SPEARS CPVC ball valves (e.g., 3632R series) for corrosive fluid isolation in piping manifolds.
