You can expect high temperature performance and good oil tolerance, a fixture time of just four minutes, and gap fill of 0.15 mm to 0.25 mm (0.006\" to 0.01\"). It even tolerates minor surface contaminants, including industrial oils. A high viscosity product, it’s ideal for shafts, gears, pulleys, and similar cylindrical parts, and can also be used for high-strength threadlocking and thread sealing applications. Operating temperature is -55°C to 180°C (-65°F to 355°F). LOCTITE 638 meets the performance requirements of KIWA GASTEC QA AR 214 for admixtures up to and including 100% hydrogen gas on metal threaded fittings – certifications are available in select countries.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eLoctite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct\u003c\/th\u003e\n\u003ctd\u003eLOCTITE 638\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAgency approvals \/ certificates \/ specifications\u003c\/th\u003e\n\u003ctd\u003eDVGW (EN 751-1): NG-5146AR0619; NSF P1 Reg.
