Our Series 5011L Straight Male Light Duty DIN x Male BSPT hydraulic adapters, made of carbon steel, combine a DIN tube fitting with a BSPT male thread. BSPT (British Standard Pipe Tapered) connections are similar to NPT connections but with slight differences in thread pitch, thread form, and outer diameter, requiring thread sealants for secure connections. The male BSPT thread features a captive seal, created through metal-to-metal angled surfaces or a combination of metal and an O-ring for added sealing security. The DIN side of the adapter adheres to ISO 8434-1 / DIN 2353 standards, utilizing a 24° tapered throat for a secure fit. Light-duty DIN adapters are typically used in lower pressure applications compared to heavy-duty DIN adapters, which are built for higher pressure systems and have a thicker, more robust construction. Thread sizes are typically expressed in fractional dimensions, with BSPT threads designated by "R" (e.g., BSPT 1/4-19 is marked as R 1/4).
