Is the Adjustable 90° Nipple with BSP Male Thread for Metric Pipe, Stainless Steel, M769LG compatible with PTFE-lined or chemically aggressive tubing?

Yes — the Adjustable 90° Nipple with BSP Male Thread for Metric Pipe, Stainless Steel, M769LG is compatible with PTFE-lined and chemically aggressive tubing in typical industrial applications. Made from AISI 316 stainless steel and engineered for use in chemical, petrochemical, pharmaceutical, energy, nuclear and process engineering environments, the fitting offers excellent corrosion resistance and compatibility with aggressive media. Its leak-tight LET-LOK® design and robust construction make it suitable for use with PTFE-lined tubing or other chemically resistant linings, provided that the tubing’s mechanical specifications (outer diameter, wall thickness, and temperature/pressure ratings) match the fitting’s requirements. Important: final compatibility depends on the specific chemical, temperature and pressure conditions and the tubing manufacturer’s recommendations. Verify that the tubing’s OD and wall thickness conform to the fitting’s sizing and that the combined system pressure/temperature limits are acceptable before installation.

Can the Adjustable 90° Nipple with BSP Male Thread for Metric Pipe, Stainless Steel, M769LG be used with high-temperature or steam applications?

Yes — Adjustable 90° Nipple with BSP Male Thread for Metric Pipe, Stainless Steel, M769LG can be used in high‑temperature and steam applications, with qualifications. Why: it is manufactured from AISI 316 stainless steel, which provides good high‑temperature strength and excellent resistance to corrosion and aggressive media common in steam and many high‑temperature processes. Its design is intended for demanding industrial environments (chemical, petrochemical, pharmaceutical, energy, nuclear, process engineering), and it provides leak‑tight integrity when installed correctly. Qualifications/limits: - Maximum safe temperature and pressure are governed by the tubing material, outer diameter and wall thickness, and the specific PED/API/ASME limits for the system. The fitting’s working pressure is determined by the tubing used, not a fixed universal value. - For saturated steam or very high temperatures, verify AISI 316 suitability for the exact temperature, pressure and media involved (creep, annealing, corrosion mechanisms can arise at elevated temperatures). - Confirm compatibility with any system codes, joint assembly procedure, and gasket/seal materials (if any) used in your installation. - For critical or nuclear applications, follow project specifications and perform engineering verification or testing as required. Recommendation: consult the tubing manufacturer’s pressure–temperature charts and your engineering standards to confirm specific temperature/pressure ratings for the intended steam service before installation.
