Mason Industries is proud to announce that our V flexes (VGN, VFL, VWN, VMN & VCPSB) and Straight flexes (MN, FFL, GN, GNF and CPSB) have passed the stringent UL (Underwriters Laboratories) testing and are now certified for use for both Wet & Dry Fire Protection Systems. To receive this prestigious certification, our material was subjected to many tests including stress, flexure, low temperature and high pressure testing. Data is also published on in-house testing of all configurations to determine safe working pressures as well as spring rates, allowable movements and thrust. UL approved products must be used in all fire protection systems designed to conform with the stringent NFPA 13 (National Fire Protection Agency) code. We have included every possible end condition in the certification. (Grooved, Threaded, Welded, and both ASA 150 and 300 lb flanges) to simplify your installation. UL Stock V flexes have 4″ all directional movement capability so they are a great solution for fire protection piping crossing building expansion joints and space between adjacent buildings, in static and seismic zones. Thermal movements are a given. All Straight flexes are the most flexible in the market place because of our close pitched corrugations. They can be used anywhere in the fire protection system too. Here again we offer the most options to the installer with 3 stock lengths and multiple end fittings. All products are available for immediate shipment.
We have the match for all your flexible piping requirements.
