Description
Schedule 80 PVC Union 2000 FKM (FPT x MPT)
Schedule 80 PVC Union 2000 FKM (FPT x MPT) provides a removable threaded connection between compatible male- and female-threaded components. The FPT end accepts a compatible male pipe thread, while the MPT end mates with a compatible female pipe thread.
The FPT x MPT union configuration combines female- and male-threaded connection interfaces with FKM sealing material. Selection should account for nominal size, Schedule 80 PVC compatibility, mating thread configurations, FKM compatibility, thread alignment, sealing requirements, piping support, and available service clearance.

Union Design
The union configuration provides a connection point that can be separated when access to adjoining piping or equipment is required. This can simplify servicing or piping changes because the connection can be opened without cutting the connected piping.
The union should be positioned where there is adequate room for assembly, disassembly, and future access. Adjoining components should be aligned and supported so the union is not relied upon to correct offsets or carry unnecessary mechanical loads.
FPT & MPT Connections
The FPT connection accepts an appropriately sized compatible male pipe thread, while the MPT connection mates with a compatible female pipe thread. Both threaded interfaces should be matched carefully to the adjoining components before assembly.
Threaded components should be started carefully and kept properly aligned during installation. Compatible thread-sealing materials and controlled assembly help establish the connections while reducing unnecessary mechanical stress on the union and adjoining components.
Schedule 80 PVC Integration
The Schedule 80 PVC construction allows the union to integrate into compatible Schedule 80 PVC piping arrangements requiring FPT x MPT connections. Matching the nominal size and both threaded interfaces to the adjoining components helps maintain the intended piping configuration.
Application suitability should be evaluated using the requirements of the complete piping system rather than the schedule designation alone. Intended service conditions, adjoining materials, thread compatibility, sealing materials, piping support, installation environment, and applicable practices should all be considered during fitting selection.
FKM Sealing Configuration
The FKM sealing material is part of the union sealing configuration and should be evaluated for compatibility with the intended service. Seal-material selection can depend on the conveyed media, temperature, operating conditions, and other application requirements.
The sealing surfaces and FKM seal should be inspected before assembly and kept free from damage or contamination. The union should be assembled evenly so the sealing components remain correctly positioned during installation and future servicing.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the FPT x MPT arrangement.
- Check Schedule 80 PVC compatibility.
- Confirm FKM suitability for the application.
- Allow adequate clearance for union servicing.

Our PVC fitting specialists can help review your nominal size, Schedule 80 requirements, FPT x MPT configuration, FKM sealing material, mating threaded components, thread compatibility, union orientation, piping alignment, support requirements, and available service clearance before you order.
Frequently Asked Questions
What is a Schedule 80 PVC Union 2000 FKM used for?
It provides a removable threaded connection between compatible male- and female-threaded components.
What does FPT mean?
FPT means Female Pipe Thread and identifies an internally threaded connection designed to accept a compatible male pipe thread.
What does MPT mean?
MPT means Male Pipe Thread and identifies an externally threaded connection designed to mate with a compatible female pipe thread.
What does FKM identify?
FKM identifies the specified sealing material used in the union and should be checked for compatibility with the intended application.
Why use a union connection?
A union provides a connection point that can be separated for access or servicing without requiring adjoining piping to be cut.
What should I confirm before ordering?
Confirm the nominal size, FPT x MPT arrangement, Schedule 80 PVC compatibility, FKM sealing requirements, and mating threaded components.
Important Ordering & Installation Notes
- Inspect both threads before use.
- Confirm the nominal connection size.
- Verify FKM compatibility for the application.
- Start threaded components carefully by hand.
- Allow clearance for future union servicing.
