Mason Industries is proud to announce that our braided hoses have passed the stringent UL (Underwriters Laboratories) testing and are now certified for use for Wet & Dry Fire Protection Systems. To receive this prestigious certification our material was subjected to many tests including stress, flexing, low temperature and high pressure testing. We have also completed extensive in house testing on all our materials to determine safe working pressures as well as spring rates and allowable movements.

UL approved products are acceptable on all fire protection systems designed to the stringent NFPA 13 (National Fire Protection Agency) code requirements. We have included every possible attachment in the certification, including grooved, threaded, welded, and ASA 150 and 300 lb flanges, so you are covered regardless of how you decide to install your system.
