Description
Schedule 80 PVC FKM Union 2000 (FNPT x FNPT)
Schedule 80 PVC FKM Union 2000 (FNPT x FNPT) provides a removable connection between compatible male-threaded piping components while incorporating female pipe threads at both ends. The Union 2000 configuration creates a serviceable connection point that can be separated at the union body without rotating or cutting the adjoining piping.
The FNPT x FNPT configuration combines two female-threaded interfaces with an FKM sealing element and a removable mechanical union joint. Selection should account for nominal size, Schedule 80 PVC compatibility, mating male pipe threads, FKM seal compatibility, intended service conditions, thread-sealing requirements, piping alignment, maintenance access, and available installation clearance.

Union 2000 Design
The Union 2000 configuration creates a mechanical separation point between adjoining threaded components within a Schedule 80 PVC piping arrangement. Once the union ends are connected to their mating components, the central union joint can be disassembled independently, allowing the piping connection to be separated without cutting the surrounding pipe.
This serviceable design can be useful near valves, equipment, instruments, or other components that may require future removal or maintenance. Maintaining adequate clearance around the union helps preserve access to the mechanical joint while allowing the adjoining piping and connected components to remain properly supported during servicing.
FKM Sealing Element
The FKM sealing element provides the seal within the removable union joint when the fitting is correctly assembled. FKM compatibility should be evaluated for the intended application because elastomer suitability can depend on the conveyed media, concentration, operating temperature, and other conditions present within the piping system.
The sealing element and its mating surfaces should remain clean, correctly positioned, and free from damage during installation or maintenance. Inspecting these areas whenever the union is opened helps identify contamination, displacement, wear, or other conditions that could interfere with proper sealing after the fitting is reassembled.
FNPT x FNPT Connections
The FNPT x FNPT configuration provides internally threaded connections at both ends of the union for compatible male-threaded components. This arrangement allows the union to be installed between threaded piping components while retaining a separate mechanical joint at the center for future disassembly and servicing.
Each mating male thread should be started carefully and kept properly aligned throughout assembly to reduce the risk of cross-threading or unnecessary loading on the PVC fitting. Compatible thread-sealing materials and appropriate tightening practices should be used while avoiding excessive force on the female-threaded union ends.
Serviceable Threaded Connection
A Schedule 80 PVC FKM Union 2000 provides a practical connection where threaded components may need to be separated without rotating the entire adjoining piping assembly. Opening the central union joint provides a convenient service point while the FNPT ends remain connected to their respective male-threaded components.
Application suitability should be evaluated using the requirements of the complete piping system rather than the Schedule 80 designation alone. FKM compatibility, mating thread requirements, service conditions, sealing materials, piping support, maintenance access, installation environment, and applicable installation practices should all be considered during union selection.
Installation & Selection Considerations
- Confirm the nominal size.
- Verify FKM seal compatibility.
- Match both mating male pipe threads.
- Check Schedule 80 PVC compatibility.
- Allow adequate access for future union service.
Our PVC fitting specialists can help review your nominal size, Schedule 80 requirements, FNPT x FNPT connections, mating male threads, FKM seal compatibility, intended service conditions, thread-sealing requirements, piping support, maintenance access, and available installation clearance before you order.
Frequently Asked Questions
What is a Schedule 80 PVC FKM Union 2000 used for?
It provides a removable connection between compatible male-threaded components within a Schedule 80 PVC piping arrangement.
What does FNPT x FNPT mean?
FNPT x FNPT means the union provides female pipe-threaded connections at both ends for appropriately sized compatible male threads.
What does FKM identify?
FKM identifies the elastomer material used for the sealing element within the removable union joint.
Why use a union in a threaded piping connection?
A union provides a mechanical separation point that allows connected piping or equipment to be separated without cutting the adjoining piping.
Can the union be opened without rotating the connected piping?
Yes. The central union joint is designed to separate while the threaded union ends remain connected to their adjoining components.
What connects to the FNPT ends?
Each FNPT connection accepts an appropriately sized compatible male pipe-threaded component.
Important Ordering & Installation Notes
- Inspect threads before use.
- Keep sealing surfaces clean.
- Start mating threads carefully by hand.
- Seat the FKM seal before final assembly.
- Support adjoining piping during union service.
