O-Ring Face Seal adapter [ORFS] fittings use a straight thread with a machined groove in the face of the male fitting to accept an O-Ring. Combined with a female fitting, this creates a leak-proof seal. Topol Power manufactures a comprehensive range of precision dapters to accommodate diverse hydraulic configuration requirements.
