Tapco A912809-0070A O-ring Tailpiece Flow Valve

Product Description

The TAPCO A912809-0070A is an O-ring designed for use on the adjustable tailpiece of a flow valve assembly. O-rings in this application create a reliable seal between threaded or sliding components, preventing fluid leakage at the tailpiece connection point. This part is a small but critical sealing element — when the original O-ring wears, cracks, or deforms, the joint loses its seal and the valve assembly can no longer hold pressure properly. Plumbers and service technicians replace this component during routine valve maintenance or when addressing leaks at the tailpiece. At 0.01 pounds, this is a lightweight replacement part intended for single-unit service use.

This O-ring is suited for use in valve assemblies where an adjustable tailpiece requires a fluid-tight seal. It is appropriate for residential and light commercial plumbing applications where flow valve servicing is performed. Technicians typically encounter this part during maintenance of fixture supply stops, inline flow valves, or similar assemblies. The part is installed as an OEM-style replacement, restoring original sealing performance when the factory O-ring has failed or deteriorated.

Key Features

• Seals the adjustable tailpiece connection on compatible flow valve assemblies
• OEM-style replacement restores original leak-free performance
• Lightweight at 0.01 pounds for easy handling and single-service use
• Designed for the tailpiece adjustment point where seal integrity is critical to valve function

Compatibility

Designed as an OEM-style replacement O-ring for TAPCO flow valve assemblies requiring an adjustable tailpiece seal. Consult the original valve documentation or cross-reference the assembly part number to confirm fitment before installation.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Shut off the water supply and relieve system pressure before disassembling the valve tailpiece. Inspect the seating surface for scoring or debris that could compromise the new O-ring seal. Avoid using petroleum-based lubricants on rubber O-rings — use only lubricants rated compatible with the O-ring material and system fluid.
