Is the Brass Tee Fitting for Metric Tubing, M764L compatible with AISI 316 stainless steel LET-LOK® tubing systems and suitable for chemical or high-temperature applications?

Yes. The Brass Tee Fitting for Metric Tubing, M764L is compatible with AISI 316 stainless steel LET-LOK® tubing systems and is suitable for chemical and high-temperature applications. Manufactured from premium AISI 316 stainless steel, the LET-LOK® tee fitting provides excellent corrosion and chemical resistance and withstands extreme operating conditions typical of chemical, petrochemical, pharmaceutical, energy and process-engineering environments. Its robust construction ensures long-term durability and leak-tight connections; working pressure capacity is determined by the tubing’s outer diameter and wall thickness, allowing proper selection for high-pressure or high-temperature service.

Does the Brass Tee Fitting for Metric Tubing, M764L meet compatibility and sealing requirements when used with AISI 316 stainless steel LET-LOK® tee fittings in corrosive or high-temperature processes?

No. Brass Tee Fitting for Metric Tubing, M764L is not recommended for use with AISI 316 stainless steel LET-LOK® tee fittings in corrosive or high‑temperature processes. The LET-LOK® tee is specified as a high‑performance AISI 316 stainless steel component with excellent corrosion and high‑temperature resistance; mating it with a brass fitting (M764L) creates a dissimilar‑metal interface that can promote galvanic corrosion in aggressive chemical environments or where moisture/electrolytes are present. Additionally, brass has lower temperature and chemical resistance than AISI 316 stainless steel, which can compromise sealing integrity and long‑term durability under extreme conditions. Compatibility and leak‑tight performance depend on matched materials, tubing dimensions, and wall thickness; for corrosive or high‑temperature applications, use matching AISI 316 fittings or materials with equivalent corrosion and thermal properties to ensure reliable sealing and service life.
