Is the HAMMER LUG connector (set) for welding, 4130 steel, type 602 suitable for air, gas, and oil at 6000 PSI with its NBR edge seal?

Yes. The HAMMER LUG connector (set) for welding, 4130 steel, type 602 is specified for general use with air, gas and oil and rated to 6000 PSI (414 bar). Its primary sealing is metal-to-metal (cone) with an additional replaceable NBR edge seal that reduces vibration of the flowing medium and protects the metal seal surfaces. Given the stated materials (4130 chromium-molybdenum steel) and the explicit application and pressure rating in the product description, the connector is suitable for air, gas and oil service at 6000 PSI using the NBR edge seal. Note: Confirm compatibility of NBR with your specific gas or oil type and operating temperature range, and follow proper welding and installation procedures to maintain the rated pressure performance.

Can the HAMMER LUG connector (set) for welding, 4130 steel, type 602 operate safely at varying temperatures with its NBR edge seal?

Yes - the HAMMER LUG connector (set) for welding, 4130 steel, type 602 can operate safely across typical industrial temperature ranges if the NBR edge seal is used within its material limits. NBR (nitrile rubber) generally performs well from roughly -30 Â°C to +100 Â°C; outside that range its elasticity, sealing ability and resistance to pressure cycling can degrade (becoming hard/brittle at low temperatures and soft/ swell/age at high temperatures), which may compromise the additional edge seal though the primary metal/metal cone seal remains intact. For elevated chemical exposure, aggressive fluids, or temperatures beyond the NBR window, specify a different elastomer or rely solely on the metal/metal seal. Always verify application temperature, fluid compatibility and perform qualification testing for your operating conditions.

Does the HAMMER LUG connector (set) for welding, 4130 steel, type 602 include replacement NBR edge seals in the set?

Does the HAMMER LUG connector (set) for welding, 4130 steel, type 602 include replacement NBR edge seals in the set? No. The HAMMER LUG connector (set) for welding, 4130 steel, type 602 includes a male part, a female part and a nut, and it features a replaceable NBR edge seal as part of the connectorâs design, but the set does not list separate replacement NBR edge seals as included.
