Frequently Asked Questions

What is the difference between metric and BSP hydraulic O-rings and seals?

Metric O-rings conform to dimensional standards such as ISO 3601 or DIN 3771 using millimeter-based sizing, while BSP (British Standard Pipe) seals are sized to British Standard pipe thread specifications. Both are widely used in hydraulic systems, but the correct type depends on your fitting standard. Detroit Sealing Components supplies both formats in NBR, FKM, EPDM, and HNBR materials.
