Is the HAMMER LUG connector (set) for welding, 4130 steel, type 1502 rated for 15000 PSI and suitable for choke and kill, fracturing, and cementing operations?

Yes. The HAMMER LUG connector (set) for welding, 4130 steel, type 1502 is rated for 15,000 PSI (1,034 bar) and is specified as suitable for choke and kill connections, fracturing, and cementing operations. The set includes male and female parts plus nut, is made of chrome-molybdenum 4130 steel for high mechanical resistance, uses a welding connection, and features metal/metal (cone) sealing with an additional NBR edge seal.

Does the HAMMER LUG connector (set) for welding, 4130 steel, type 1502 use NBR edge seals in addition to metal/metal cone sealing?

Yes. The HAMMER LUG connector (set) for welding, 4130 steel, type 1502 uses metal/metal (cone) sealing plus an additional NBR edge seal.

Can the HAMMER LUG connector (set) for welding, 4130 steel, type 1502 be used for high-temperature applications?

No. the HAMMER LUG connector (set) for welding, 4130 steel, type 1502 is not intended for highâtemperature service. The description specifies sealing by metal/metal cone plus an additional NBR (nitrile rubber) edge seal. NBR has limited heat resistance (typically up to ~100â120Â°C continuous; short peaks higher but not suitable for true highâtemperature environments). While the 4130 chromeâmoly steel body has good mechanical strength and higher temperature capability than mild steels, the presence of the NBR edge seal makes the assembly unsuitable for applications where elevated temperatures would degrade the elastomeric seal. For highâtemperature use you would need a connector with a highâtemperature elastomer (e.g., Viton, PTFE, graphite, or allâmetal sealing) and validated temperature ratings. Pressure rating (15000 PSI / 1034 bar) addresses mechanical capability but does not override the temperature limitation imposed by the NBR seal.
