Prier Products 630-7066 Ballcock Service Kit

Product Description

The PRIER PRODUCTS 630-7066 is a ballcock service kit designed to restore proper float-valve operation in compatible Mansfield toilet fill valves. The kit supplies the internal wear components most likely to fail over time, including a nylon seat, a neoprene valve seat, a huva-cup seal, and two thumb screws. Plumbers and skilled DIYers use this kit to rebuild an existing ballcock assembly rather than replace the entire fill valve, saving time on residential toilet repairs. All components are sized to fit the designated Mansfield models directly out of the package.

This service kit is intended for residential toilet tank applications where the existing ballcock is leaking, running continuously, or failing to shut off at the correct water level. It is a direct-fit rebuild solution that eliminates the need to remove and replace the full fill valve assembly, making it a practical choice for service calls where minimizing parts cost and labor time matters.

Key Features

• Includes nylon seat for durable, corrosion-resistant sealing contact
• Neoprene valve seat provides reliable water-tight closure under normal line pressure
• Huva-cup seal replaces the primary cup that controls water flow shutoff
• Two thumb screws included for complete hardware replacement during rebuild
• Single-unit packaging with a minimum order quantity of one kit

Compatibility

Designed for use with Mansfield model No. 03, 09, and X0-16 ballcocks.

Installation Notes

Installation is performed by a licensed plumber or qualified technician. Shut off the water supply to the toilet at the angle stop valve and flush to drain the tank before beginning disassembly. Inspect the ballcock body for cracks or damage before installing new kit components, as a compromised body will not be corrected by a service kit. Follow all applicable IPC guidelines for potable water fixture repair.
