Furon® Tongue & Groove Sealing Systems - Maximum Pressure Resistance Report
August 07th, 2018
Furon® SSUM (Single Seal System) and DSUM (Dual Seal System) fittings, generally used in a FuseBond™ or welded installation of PFA pipe, were tested side by side for maximum pressure resistance.
In this analysis, Furon 2-inch valves were used to test the efficiency and reliability of both the Furon SSUM and Furon DSUM fittings in a complex environment. A tight 88.5 lbs/in torque connection was applied before tabs were set into position. Then the connections were plugged into 100 PSIG Clean Dry Air (CDA) and immersed in water to monitor any bubbles created during a one minute period. If a single bubble was created during this time, the product was rejected. The components were then installed on a vibrating bench and the Furon valves were cycled in order to increase stress on the connections.
Maximum Pressure Test
For this analysis, the Furon SSUM and DSUM fittings were connected to a liquid pumping system, allowing a slow but consistent pressure increase starting at 0 PSIG up to 310 PSIG. The test was performed in a controlled environment at 72°F +/-1.
