Buying Guide

Match part to flushing system

Confirm whether you have a flushometer, pressure-assisted, or tank canister design to ensure diaphragm, cartridge, or seal compatibility

Check gallons-per-flush (GPF)

Select diaphragms or assemblies rated for your fixture's GPF (1.0, 1.28, 1.5, 3.5, etc.) to maintain proper flush performance and compliance

Prioritize OEM or OEM-equivalent fit

Choose parts from original manufacturers or exact-fit replacements to reduce installation time and prevent leaks

Inspect materials for longevity

Look for durable elastomers and corrosion-resistant components for frequent-use commercial fixtures like urinals and flushometers

Consider pack size and spare parts

Multipacks or tune-up kits provide extra seals or diaphragms that simplify future maintenance and lower per-replacement effort
