Can the Straight Stainless Steel Bulkhead Fitting for Metric Tubing, M774L withstand high temperatures and extreme pressure variations in industrial systems?

Straight Stainless Steel Bulkhead Fitting for Metric Tubing, M774L: Yes — the M774L is engineered to withstand high temperatures and significant pressure variations typical of demanding industrial systems. Made from AISI 316 stainless steel, it offers excellent resistance to heat and aggressive chemicals, ensuring structural integrity under extreme operating conditions. However, the maximum working pressure is not a fixed value of the fitting alone; it is determined by the specific metric tube’s outer diameter and wall thickness used in the installation. For safe specification, consult the tube pressure ratings at your operating temperature and match them to the M774L installation guidelines and industry standards. When selected and installed per manufacturer recommendations, the M774L provides durable, reliable performance in chemical, petrochemical, pharmaceutical, energy, nuclear, and process-engineering applications.
