Product Highlights

• PVC construction
• Schedule 80 design
• EPDM sealing element
• Union 2000 configuration
• Socket x FPT connections
• Provides a removable transition connection
• Joins PVC pipe to a compatible male thread
• Supports serviceable connections in Schedule 80 PVC piping systems

The Union 2000 configuration creates a serviceable separation point between the socket and female-threaded sides of the fitting. Once the end connections are installed, the central union joint can be opened independently so adjoining piping or equipment can be separated without cutting the solvent-cemented PVC pipe.

This removable arrangement can simplify appropriate maintenance, equipment replacement, and piping access where future disconnection is expected. Adequate working clearance should be maintained around the union so the mechanical joint remains accessible while adjoining piping and connected components are independently supported during servicing.

The EPDM sealing element provides the seal within the removable union joint when the fitting is properly assembled. Because elastomer suitability varies by application, EPDM compatibility should be evaluated against the conveyed media, temperature, concentration, and other service conditions expected within the completed piping system.

The EPDM element and mating sealing surfaces should remain clean, correctly positioned, and free from damage whenever the union is assembled or serviced. Inspecting these components during maintenance helps identify contamination, displacement, wear, or deterioration that could interfere with sealing when the union is returned to service.

The Socket x FPT configuration provides two different connection interfaces within one union. The socket side receives appropriately sized compatible PVC pipe for solvent-cement joining, while the female pipe-threaded side accepts an appropriately sized compatible male-threaded component for a mechanical threaded connection.

Each connection should be assembled according to its specific joining method rather than treating both ends alike. Proper socket preparation, careful thread engagement, compatible joining and sealing materials, and natural piping alignment help protect the fitting while establishing the intended transition between the two connection styles.

A Schedule 80 PVC EPDM Union 2000 (S x FPT) provides a practical transition where compatible PVC pipe must connect to a male-threaded component while retaining a removable service point. The union joint separates independently, allowing the socket and threaded ends to remain connected to their respective adjoining components.

Application suitability should be evaluated using the requirements of the complete piping system rather than the Schedule 80 designation alone. EPDM compatibility, adjoining pipe and thread requirements, service conditions, joining materials, piping support, maintenance access, installation environment, and applicable installation practices should all be considered during selection.

• Confirm the nominal size.
• Verify EPDM compatibility.
• Match the mating male pipe thread.
• Check Schedule 80 PVC compatibility.
• Allow adequate clearance for future union service.
