Union (O-Ring Type), Slip x FPT 1" (9899-010)
$28.38
The 1" PVC Union (O-Ring Type, Slip x FPT) offers a re-joinable connection point with a mixed-end configuration — a solvent-weld slip socket on one end and a female pipe thread (FPT) port on the other. This combination makes the 9899-010 particularly versatile in systems where one side of the union connects permanently to a solvent-welded pipe run while the other interfaces with a threaded valve, equipment port, or MPT adapter.
Like all O-ring style unions, the sealing mechanism relies on a captured elastomeric O-ring compressed at the union's mating face rather than a flat face-to-face contact seal. This design maintains a reliable, leak-free joint across repeated assembly and disassembly cycles — making it the preferred union style wherever the connection will be broken regularly for maintenance, equipment swaps, or seasonal system changes. Once both end bodies are installed, the system can be disconnected and reconnected at the union nut without disturbing either the solvent-welded or threaded connections upstream and downstream.
At 1", this union is well-suited for pump systems, chemical feed equipment, filtration assemblies, and any inline component requiring periodic removal in a small-diameter PVC system. The slip x FPT configuration reduces the need for additional transition fittings, keeping the installation compact and the fitting count low.

Industries & Applications:
- Pump Systems — Installed on suction or discharge side of small pump assemblies where one connection is solvent-welded into the pipe run and the other interfaces with a threaded pump port or valve body; allows pump removal without cutting pipe
- Chemical Feed & Dosing — Provides a re-joinable access point in chemical metering and dosing lines where PVC's chemical resistance is required and equipment must be periodically removed for calibration or replacement
- Water Treatment & Filtration — Used at filter housings, UV units, and cartridge filter vessels with threaded ports; the slip side bonds permanently into the supply line while the FPT side accepts the equipment's threaded inlet
- Commercial Plumbing — Applied at equipment isolation points in small-diameter service lines where a mixed solvent-weld and threaded transition union reduces fitting count and simplifies future servicing
- Irrigation Systems — Installed at controller valves, filter stations, and fertigation injectors where a permanent slip connection on the mainline side and a threaded equipment connection on the device side are required
- Aquaculture & Laboratory Piping — Suits recirculating system components and laboratory equipment with threaded inlets that must be disconnected regularly without disrupting the surrounding solvent-welded piping network
