Spears CPVC CTS Union Fitting, Socket, EPDM Seal

The Spears CPVC CTS Union Fitting is a socket-connection union built for CPVC CTS (Copper Tube Size) piping systems, engineered with an EPDM seal to deliver a dependable, leak-resistant joint at every union point. As a three-piece union, it lets installers and maintenance crews disconnect and reconnect sections of CPVC pipe without cutting the line, which makes future service, repairs, and system modifications far easier than with a fixed, solvent-welded run alone. Molded from CPVC and sized to CTS dimensional standards, this Spears union is intended to integrate cleanly with existing CPVC CTS plumbing systems. It ships packaged 48 pieces per case, a quantity suited to distributors, contractors, and maintenance facilities that need a ready supply of union fittings on hand for ongoing plumbing work.

Key Features

  • Socket Connection: Solvent-weld socket ends provide a secure, permanent bond to CPVC CTS pipe for a solid, leak-resistant joint.
  • CTS Sizing: Dimensioned to CPVC CTS (Copper Tube Size) standards so it aligns with the sizing convention used throughout CTS-based CPVC plumbing systems.
  • EPDM Seal: An EPDM seal at the union joint helps maintain a reliable seal against leaks through repeated assembly and disassembly.
  • Union Design: The three-piece union body allows the fitting to be taken apart and reassembled, so a section of pipe or an adjoining fixture can be serviced without cutting into the surrounding CPVC line.
  • Durable Construction: Molded from CPVC, a rigid thermoplastic commonly selected for hot and cold water distribution lines where corrosion resistance is a priority over metallic piping.
  • Case Packaging: Supplied 48 pieces per case, simplifying stocking and bulk ordering for distributors and installation crews.

Spears 4197-010 – Frequently Asked Questions

1) How does this union connect, threaded or solvent weld?
Both ends are solvent-weld sockets, so the union halves cement permanently onto the CPVC tube. The union nut in the middle is what you break loose for service, not the pipe joints. You will need CPVC solvent cement and primer appropriate to the pipe, which are not included with the fitting.
2) Can I use this CPVC union to transition to copper or PEX?
No. Both ends of the 4197 are CPVC solvent-weld sockets sized to CTS CPVC tube, so it joins CPVC to CPVC only. For a copper or PEX transition you need a dedicated transition fitting, typically a CPVC socket by female or male thread adapter paired with the appropriate metal or PEX adapter on the other side.
3) What sizes does the Spears 4197 CPVC CTS union come in?
Two sizes: 3/4 inch (part 4197-007) and 1 inch (part 4197-010). Both are socket-by-socket unions for solvent welding to CPVC CTS tube.
4) Why put a union in a CPVC water line instead of just solvent welding it straight through?
A union gives you a planned break point. With a three-piece union at a water heater, pump, valve, or fixture drop, maintenance crews can disconnect and reconnect that section without cutting the CPVC line and re-cementing couplings. Property managers and MRO crews typically set them where a component gets replaced on a cycle, so the same joint can be opened repeatedly.
5) Is the EPDM seal in this union okay for hot water?
EPDM is the seal material in the 4197 union, and the fitting is intended for CPVC hot and cold water distribution lines. CPVC itself is the material selected for hot water service where corrosion resistance matters over metallic pipe. Note that EPDM is a water-service elastomer, not a petroleum-service one, so keep it to potable and hydronic water rather than oil-based media.
6) Is the Spears CPVC CTS union sold individually or by the case?
It is supplied 48 pieces per case, which suits distributors, contractors, and maintenance shops stocking union fittings for ongoing CPVC work rather than a one-off repair.
7) Where can I get the socket depth and laying length dimensions for this Spears CTS union?
Spears publishes the CTS CPVC dimensional data and product weights for this family, and ZenSupply carries those sheets with the fitting: the CTS CPVC Dimensions sheet and the CPVC CTS product dimensions and weights sheet. Use those for socket depth and overall length when you are laying out a tight rough-in.
