Delany Products F141-KC Diaphragm Closet Kit 4.5 Gpf

Product Description

The DELANY PRODUCTS F141-KC is a diaphragm closet flush valve rebuild kit rated at 4.5 gallons per flush (GPF). It provides replacement diaphragm components for commercial-grade closet flush valves, restoring proper flush performance and sealing function. This kit is intended for licensed plumbers and commercial maintenance technicians servicing flush valve assemblies in restroom facilities. Rebuilding the diaphragm assembly rather than replacing the entire valve body is a standard service approach that reduces material cost and downtime in high-traffic restroom environments.

This kit is suited for commercial and institutional restroom applications where Delany flush valves are installed on water closets. Typical install scenarios include office buildings, schools, hospitals, and other facilities running high-cycle flush valve systems. The 4.5 GPF flow rate is consistent with older or high-flush commercial closet valve specifications. Technicians servicing aging flush valve infrastructure will find this a direct-replacement diaphragm solution for applicable Delany valve bodies.

Key Features

• Rated at 4.5 GPF for commercial water closet flush valves
• Rebuild kit format allows in-place valve service without full valve body replacement
• Designed for closet (water closet) flush valve applications
• Manufactured by Delany Products, a recognized commercial flush valve supplier

Compatibility

Installation Notes

Installation should be performed by a licensed plumber or qualified maintenance technician familiar with commercial flush valve service. Shut off the water supply to the fixture and flush the valve to relieve pressure before disassembling the valve cover. Diaphragm kits typically require no special tools beyond a adjustable wrench and are serviced per the valve manufacturer's instructions. Follow all applicable local plumbing codes and IPC guidelines when performing flush valve maintenance.
