What's New

Seal-Lok Xtreme fittings take flat face seal design to extreme temperatures with our recently patented metal seal that is capable of temperatures ranging from -65°F to +450°F (-54°C to +232°C). Now the advantages of o-ring face seal (ORFS) fittings, such as vibration tolerance, zero clearance, ease of assembly and reassembly, are available for your extreme temperature systems.
