Description
Schedule 80 PVC Union 2000 FKM (SOC x MPT)
Schedule 80 PVC Union 2000 FKM (SOC x MPT) provides a removable connection between compatible PVC pipe and a female-threaded component using socket and male pipe-threaded connections. The union configuration allows the connected piping sections to be separated at the union without requiring the adjoining pipe to be cut.
The SOC x MPT configuration combines socket and male-threaded connection interfaces with the specified FKM sealing material. Selection should account for nominal size, Schedule 80 PVC compatibility, adjoining components, connection orientation, sealing-material compatibility, joining requirements, piping alignment, and available service clearance.

Union Design
The union configuration provides a connection point that can be separated when access to the adjoining piping or equipment is required. This can simplify servicing or piping changes because the union connection can be opened without cutting the connected pipe.
The union should be positioned where there is adequate room for assembly, disassembly, and future access. Adjoining piping should be aligned and supported so the union is not relied upon to correct offsets or carry unnecessary mechanical loads.
Socket & MPT Connections
The socket connection receives appropriately sized compatible PVC pipe, while the MPT connection mates with a compatible female pipe thread. Each side requires the appropriate assembly method for its connection style while the union provides the removable connection point.
The socket surfaces should be prepared for the applicable PVC solvent-cement joining procedure, while the male-threaded connection should be started carefully and kept properly aligned. Compatible joining and thread-sealing materials should be selected for the adjoining components and intended installation.
Schedule 80 PVC Integration
The Schedule 80 PVC construction allows the union to integrate into compatible Schedule 80 PVC piping arrangements requiring SOC x MPT connections. Matching the nominal size and both connection 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, connection compatibility, sealing materials, joining materials, piping support, 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 is an important consideration because suitability can depend on the fluid, 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 and according to the requirements of the piping installation so the sealing components remain correctly positioned.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify the SOC 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, SOC x MPT configuration, FKM sealing material, adjoining PVC pipe, mating female-threaded component, joining requirements, union orientation, piping layout, 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 connection between compatible PVC pipe and a compatible female-threaded component using SOC x MPT connections.
What does SOC mean?
SOC identifies a socket-style connection designed to receive appropriately sized compatible PVC pipe.
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 configuration 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 the adjoining pipe to be cut.
What should I confirm before ordering?
Confirm the nominal size, SOC x MPT arrangement, Schedule 80 PVC compatibility, FKM sealing requirements, and adjoining components.
Important Ordering & Installation Notes
- Inspect the union before use.
- Confirm the nominal connection size.
- Verify FKM compatibility for the application.
- Align adjoining piping before final assembly.
- Allow clearance for future union servicing.
