Our Series 5009GC Straight Male DIN x Female BSPP gauge coupling hydraulic adapters are designed to connect DIN-threaded components with BSPP-threaded components in applications involving pressure gauges or similar measurement devices. The male DIN side features a 24° tapered throat inside the threads, allowing for a secure connection when the tube nut is tightened, compressing a ferrule or cutting ring to form a reliable seal. The female BSPP side, which has parallel threads, ensures a leak-tight seal through metal-to-metal contact or an O-ring. These fittings are ideal for high-pressure systems and are particularly suited for gauge connections due to their ability to withstand pressure while providing secure and accurate readings. These adapters are made from durable carbon steel and are suitable for both light-duty and heavy-duty applications.
