Is the Adapter socket for metric tube, stainless steel, M767LT compatible with tubes of different outer diameters and wall thicknesses, and how is allowable working pressure determined?

The Adapter socket for metric tube, stainless steel, M767LT is designed for metric tubes but compatibility with different outer diameters and wall thicknesses depends on the specific size version of the LET-LOKÂ® socket. Allowable working pressure is not a single fixed value for the part; it is determined from the tubeâs outer diameter (OD) and wall thickness . larger OD or thinner walls reduce allowable pressure, thicker walls and smaller OD increase it. Exact allowable working pressures for given OD/wall combinations are provided in the productâs detailed tables/attachment. Material is AISI 316 stainless steel, and the socket is intended mainly for chemical, petrochemical, pharmaceutical, energy, nuclear power and process engineering industries. For safe selection, match the socket size to your tube OD and wall thickness and consult the manufacturerâs pressure table or datasheet.

Can Adapter socket for metric tube, stainless steel, M767LT be used in nuclear applications and meet industry safety standards?

Adapter socket for metric tube, stainless steel, M767LT can be used in nuclear applications provided its specifications meet the specific system requirements and regulatory standards for the installation. The product description states it is intended for nuclear power and similar industries and is made of AISI 316 stainless steel, which offers good corrosion resistance and is commonly accepted in many nuclear systems. Critical checks before use: verify allowable working pressure for the exact tube OD and wall thickness per the attachment; confirm material suitability for the reactor environment (radiation, temperature, chemical exposure); ensure compliance with applicable nuclear codes and standards (owner/operator requirements, ASME, RCC-M or national regulations); confirm traceability, quality control, testing (e.g., NDT, material certificates) and installation procedures. If all these are satisfied, M767LT can meet industry safety standards.

What are the installation torque and sealing requirements for the Adapter socket for metric tube, stainless steel, M767LT?

Adapter socket for metric tube, stainless steel, M767LT. installation torque and sealing requirements - Sealing: The M767LT is a LET-LOKÂ® type socket designed to seal on the tube outer diameter. Use undamaged metric stainless steel tubes (AISI 316) with the specified outer diameter and wall thickness. Ensure tube end is square-cut, free of burrs, clean, and free of contamination. No additional sealing compounds are normally required; correct metal-to-metal contact and the ferrule system provide the seal. For applications requiring enhanced chemical resistance or where specified, apply only manufacturerâapproved sealants compatible with AISI 316 and the process fluid. - Installation torque: Tighten the nut progressively by hand engagement, then use a torque wrench following the LET-LOKÂ® recommended procedure: make an initial snug-up, then tighten to the specified torque based on tube outer diameter and wall thickness. Typical torque values for AISI 316 metric LET-LOKÂ® sockets (M767LT) fall within the manufacturerâs chart. always use the chart for exact OD/wall combinations. As a general guide (confirm with the product chart): - Small metric tubes (e.g., 6â10 mm OD): low torque range (approx. 10â25 Nm) - Medium metric tubes (e.g., 12â18 mm OD): medium torque (approx. 25â50 Nm) - Larger metric tubes (e.g., 22â25 mm OD and above): higher torque (approx. 50â100+ Nm) - Assembly notes: Use calibrated torque tools; avoid overâtightening which can damage ferrules or deform the tube and compromise sealing. After initial assembly, pressurize and inspect for leaks; if leakage occurs, slightly increase torque in small increments to the next recommended value from the manufacturerâs table. Reâuse of ferrules is not recommended unless explicitly allowed by the manufacturer. For safe and pressure-rated installation, consult the M767LT product chart and torque table (manufacturerâs attachment) for exact torque values corresponding to the tube outer diameter and wall thickness used.
