Connect your European British Standard Pipe threaded tools to American Industrial National Pipe Tapered Thread couplings with this quarter-inch adaptor fitting BSP (Male) to NPT (Female). These Martins Industries air tool adaptors have tapered threads and are sold in pairs. Due to the tapered threads, these adaptors have sturdy seals, so the connections are not only strong but also leak-resistant. These adaptors are made of brass, ensuring long-term use and durability; brass is a very strong metal, as it is an even harder metal than steel. These adaptors are extremely lightweight. These adaptors are great to use for tire equipment, so pair them with your other Martins Industries gear in order to enhance efficiency; these adaptors are especially compatible with impact wrenches, such as the powerful ones produced by Martins Industries. The versatility of these adaptors allows for use in tire shops, dealerships, collision centers, garages, manufacturing facilities, job sites, and so much more.
