Is the HAMMER LUG connector (set) with GW NPT, carbon steel, type 206 suitable for use with oily hydraulic fluids at 138 bar (2000 PSI)?

Yes. The HAMMER LUG connector (set) with GW NPT, carbon steel, type 206 is suitable for use with oily hydraulic fluids at 138 bar (2000 PSI). The product description explicitly lists oil among its applications, specifies a working pressure of 2000 PSI (138 bar), and features sealing by metal/metal cone plus an additional NBR gasket (oilâresistant elastomer) and an Oâring to enhance sealing and lifespan. Carbon steel A105 construction is typical for hydraulic fittings; however, ensure compatibility of NBR with your specific hydraulic fluid and verify corrosion protection (coating or material suitability) for your operating environment.

Can the HAMMER LUG connector (set) with GW NPT, carbon steel, type 206 be used for steam or hot water applications at 138 bar (2000 PSI)?

Based on the provided description, the HAMMER LUG connector (set) with GW NPT, carbon steel, type 206 is rated to 2000 PSI (138 bar) and is designed for transmission of water, air, gas and oil. It features metal-to-metal cone sealing plus an additional NBR gasket and an Oâring for enhanced sealing and lifespan. Therefore it can be used for steam or hot water at that pressure only if the NBR gasket and Oârings, and the carbon steel A105 material, are compatible with the steam temperature and chemical conditions. NBR typically degrades at high steam temperatures; A105 may be susceptible to corrosion/temper embrittlement with steam. Recommendation: verify maximum operating temperature limits for the NBR seal and A105 in steam service with the manufacturer before use.

Can the HAMMER LUG connector (set) with GW NPT, carbon steel, type 206 be used for corrosive gases at 138 bar (2000 PSI)?

Not recommended without further compatibility verification. Reasoning: - The HAMMER LUG connector (set) with GW NPT, carbon steel, type 206 is rated for 2000 PSI (138 bar) and uses carbon steel A105 construction with a metal/metal (cone) primary seal plus an additional NBR (nitrile) gasket and an O-ring for improved sealing. Mechanically, the pressure rating is adequate for 138 bar. - Corrosive gases pose two separate concerns: material corrosion resistance and chemical compatibility of the elastomer sealing (NBR). Carbon steel A105 is susceptible to corrosion when exposed to many corrosive gases (e.g., H2S, chlorine, ammonia, certain halogenated compounds, acidic vapors) unless protected by coatings, inhibitors, or a suitable isolation method. NBR degrades with exposure to some chemicals (strong oxidizers, certain hydrocarbons, acids, ketones), which can compromise the secondary seal and lead to leaks. - The product description does not specify suitability for corrosive service, corrosion allowances, protective coatings, or alternative elastomers. Recommendation: - Do not assume safe use with corrosive gases based solely on the provided description. Consult the gas chemical compatibility data, your process conditions (temperature, concentration, presence of moisture, cyclic pressures) and the manufacturer/supplier for explicit approval or alternative materials (stainless steel, corrosion-resistant alloys, or compatible elastomers such as FKM, EPDM, or PTFE) and any required protective measures.
