Threaded ends are often found in the majority of hose fittings. You can only couple female with male ends (and vice-versa) if they have the same thread size. In some cases, you can't swap or switch fire fitting threads. One should also know that there can be a difference in angle and diameter. Combining two different thread types can lead to unwanted leakage and disconnect, which can create hazardous scenarios for firefighters, security
personnel, and other individuals. Varying lengths, thread types, and thread sizes of fire fittings are available here at MRO Supply. Within this range, customers can find a replacement fitting for their required applications. Talk to our customer representatives to find which one is suitable for your fire system.
