Spears 8099-020CSR 2" CPVC Union 2000 Fitting with EPDM Seal, SOCxSRFPT
The Spears 8099-020CSR is a 2" CPVC Union 2000 fitting engineered for CPVC piping systems that require a reliable, serviceable connection point. It combines a socket x SR FPT (spigot-reinforced female pipe thread) configuration with an EPDM elastomeric seal, letting technicians disconnect and reconnect pipe sections without cutting into the line, which greatly simplifies routine maintenance, inspection, and repair work. Molded from CPVC thermoplastic, the 8099-020CSR resists corrosion, scaling, and chemical attack, making it well suited for demanding fluid-handling applications where metallic fittings would otherwise degrade over time.
Key Features
- Trade Size: 2" connection sized to integrate directly into standard 2" CPVC piping runs.
- Durable Construction: CPVC material delivers strong corrosion, scale, and chemical resistance for a longer, lower-maintenance service life than metallic union fittings.
- Union 2000 Design: Three-piece union body lets the joint be broken and reassembled for maintenance, valve replacement, or component inspection without cutting or re-gluing the surrounding pipe run.
- Connection Type: Socket x SR FPT (spigot-reinforced female pipe thread) configuration provides a secure, versatile joint between solvent-welded socket pipe on one side and threaded fittings, valves, or equipment on the other.
- EPDM Seal: EPDM elastomeric union seal delivers dependable, leak-resistant sealing performance at the union face across repeated disconnect/reconnect cycles.
- System Compatibility: Designed to integrate seamlessly alongside other Spears CPVC pipe, fittings, valves, and adhesives in a single CPVC piping system.
- Reinforced Thread Design: The SR (spigot-reinforced) female thread helps distribute mechanical stress at the threaded joint, reducing the risk of thread damage versus a standard FPT connection.

Spears 8099-020CSR – Frequently Asked Questions
1) What does the SOCxSRFPT on the Spears 8099-020CSR 2 inch union mean for how I connect it?
One end of the 8099-020CSR is a solvent-weld socket that cements onto 2 inch CPVC pipe, and the other is an SR FPT, a spigot-reinforced female pipe thread that takes a male threaded fitting, valve nipple, or piece of equipment. So you glue one side and thread the other. Use CPVC solvent cement on the socket side and thread sealant or tape on the threaded side, and do not over-torque the plastic thread.
2) Can I break the union apart later without cutting the CPVC pipe?
That is the point of it. The Union 2000 is a three-piece body, so backing off the union nut separates the joint and lets you pull a valve, pump, strainer, or meter out of the line and put it back without cutting pipe or re-cementing. Put one on each side of any component you expect to service and the whole item drops out in place.
3) Will a CPVC union work on my PVC line, or do I need a PVC one?
The 8099-020CSR is molded CPVC, so it is meant for CPVC piping systems and is intended to run with Spears CPVC pipe, fittings and valves. Cementing CPVC to PVC pipe is a material mismatch in a solvent-welded system; if your run is PVC, order the PVC version of the Union 2000 in 2 inch instead. The threaded SR FPT end is a different story, a threaded joint will mate with any compatible male pipe thread regardless of what the other part is made from.
4) Is the EPDM seal in this Spears union right for my chemical or hot water service?
The 8099-020CSR ships with an EPDM elastomeric union seal at the union face, which holds up across repeated disconnect and reconnect cycles. EPDM suits water, water treatment and many aqueous chemical services. It is not the choice for petroleum products or mineral oils, where a FKM or Viton seal is the usual call, so check your fluid against the elastomer before you commit. Spears also publishes the same Union 2000 body with other seal materials if EPDM is wrong for the media.
5) What is the advantage of an SR female thread over a standard FPT on a plastic union?
The spigot-reinforced female thread on the 8099-020CSR puts extra wall behind the thread so mechanical stress at the joint spreads out instead of concentrating in the thread root. In practice that means less risk of splitting or stripping the thread when an installer leans on a wrench, which is the common failure on standard plastic FPT connections.
6) Where should I put a 2 inch CPVC union in a process or water treatment line?
Standard practice is a union immediately upstream and downstream of anything you will pull for service: control valves, pumps, filters, meters, injection points. The 8099-020CSR gives that disconnect point in 2 inch CPVC, and it is also useful on retrofit and repair work where you need to tie into an existing CPVC line and keep the option of taking it back apart. Typical service lists for it include industrial fluid handling, chemical-resistant runs, and water distribution and treatment.
7) Why use a CPVC union instead of a brass or steel union on a water treatment line?
Metallic unions corrode and scale in aggressive or chemically treated water, and once the threads seize the serviceability you paid for is gone. The 8099-020CSR is CPVC, so it resists corrosion, scaling, and chemical attack, and it keeps breaking loose cleanly cycle after cycle. That is the trade-off: you give up the mechanical toughness of metal and you gain a joint that does not degrade in the fluid.
