Is the Stainless Steel Straight Connector for Inch Pipe, C762L compatible with tubing of different OD and wall thicknesses to achieve required working pressures?

Yes. The Stainless Steel Straight Connector for Inch Pipe, C762L is compatible with tubing of different outer diameters (OD) and wall thicknesses, provided the selected tubing falls within the dimensional and material limits for which the LET-LOK® straight coupling is specified. The connector’s achievable working pressure is determined by the tubing’s OD and wall thickness: larger OD and thicker walls yield higher pressure capacity, while smaller OD and thinner walls reduce it. To ensure safe, leak-tight performance at the required working pressure, match the connector model to the tubing dimensions and material grade per the manufacturer’s pressure ratings and installation guidelines. If precise pressure values are needed for a specific tube OD/wall combination, consult the product pressure tables or contact the supplier with the tubing dimensions and service conditions for confirmation.

Can the Stainless Steel Straight Connector for Inch Pipe, C762L be used with different tubing materials (not just AISI 316) while maintaining certified leak-tight performance?

The Stainless Steel Straight Connector for Inch Pipe, C762L is manufactured from AISI 316 stainless steel and its certified leak-tight performance is specified relative to the tubing’s outer diameter and wall thickness. In practice this means: - If the alternative tubing material has identical outer diameter, wall thickness, and comparable mechanical properties (hardness, yield strength) and surface finish to the qualified AISI 316 tubing, the connector can achieve leak‑tight joints provided installation follows the same procedures and torque/assembly controls. - If the tubing material differs significantly (different hardness, elasticity, surface finish, or chemical interaction with AISI 316), leak-tight certification cannot be assumed. Materials that are much softer or harder, that cold‑work differently, or that promote galvanic corrosion with AISI 316 may change sealing behavior and require requalification. - For critical or regulated applications (chemical, pharmaceutical, nuclear, etc.), any change from the specified AISI 316 tubing should be validated by testing or approved by the manufacturer to maintain certified leak‑tight performance. Recommendation: Use the connector with tubing that matches the qualified dimensions and mechanical characteristics, or obtain manufacturer guidance and requalification testing when using different materials.
