Seal-Lok for CNG Fittings and Adapters provide reliable natural gas fuel conveyance in CNG applications with an O-ring face seal design that incorporates an elastomeric seal compound made of hydrogenated nitrile. Tested and certified by TUV for applicable industry standards, these O-ring face seal fittings offer many benefits like, zero clearance for easy plumbing, resistance to over-tightening and vibration, and unlimited remakability, which make it an ideal hydraulic fluid connection solution. Seal-Lok for CNG leak-free connections reduce warranty costs and maintenance expenditures while providing a competitive advantage for customers in the CNG market.

Seal-Lok for CNG O-Ring Face Seal (ORFS) fittings are tailored to accommodate unique natural gas attributes. They provide reliable fuel conveyance using an elastomeric seal compound made of hydrogenated nitrile that improves ozone resistance and supports wider temperature and pressure range requirements. In addition, it’s a great solution for high-vibration, on-vehicle applications where metal-to-metal sealing is not up to the task. Seal-Lok for CNG fittings are fully tested by TUV (NGV 3.1, ECER110, ISO 15500), and recently passed Bonfire Testing in accordance with ANSI/CSA NGV2

Seal-Lok for CNG ORFS fittings passed the critical Bonfire Testing required for NGV refuse trucks, ensuring the safety and reliability of these proven leak-free fittings in the harshest conditions. Read the Bonfire Test Summary for more details on this test and Seal-Lok for CNG’s performance.
