Is the Straight fitting for inch pipe, stainless steel, C762L compatible with AISI 316 tubing and the LET-LOKÂ® straight coupling type for inch tubing?

Yes. The Straight fitting for inch pipe, stainless steel, C762L is compatible with AISI 316 tubing when used with the LET-LOKÂ® straight coupling type for inch tubing. The LET-LOKÂ® straight coupling is specified for inch tubing and the product description states material AISI 316 steel for the coupling; allowable working pressure is determined by tubing outer diameter and wall thickness (see attachment). Therefore the C762L straight fitting can be used with AISI 316 tubing in LET-LOKÂ® straight coupling assemblies, provided the tubing meets the dimensional and pressure-rating requirements shown in the manufacturerâs tables.

Can the Straight fitting for inch pipe, stainless steel, C762L handle the allowable working pressures for AISI 316 inch tubing LET-LOKÂ®?

Yes - the Straight fitting for inch pipe, stainless steel, C762L can handle the allowable working pressures for AISI 316 inch tubing LET-LOKÂ® provided the tubingâs outer diameter and wall thickness fall within the pressure-rating ranges specified for LET-LOKÂ® couplings. The Straight coupling type LET-LOKÂ® for inch tubing is designed for the listed industries and its allowable working pressure is determined by tubing OD and wall thickness (as noted). Since your tubing material is AISI 316 and the fitting material is C762L, ensure the specific tubing dimensions match the pressure table in the attachment; if they do, the Straight fitting for inch pipe, stainless steel, C762L is suitable.

Does the Straight fitting for inch pipe, stainless steel, C762L meet compatibility requirements with LET-LOKÂ® AISI 316 inch tubing?

No. the Straight fitting for inch pipe, stainless steel, C762L Format is not compatible with LET-LOKÂ® AISI 316 inch tubing. Reasoning: - LET-LOKÂ® straight coupling for inch tubing is specified as being made of AISI 316 stainless steel. Compatibility for pressure ratings and sealing depends on matching material properties (including corrosion resistance, hardness, and galvanic behavior) and on the allowable working pressure calculated for the LET-LOKÂ® tubingâs outer diameter and wall thickness. - The Straight fitting for inch pipe, stainless steel, C762L Format is made of a different material (C762L, a copper-nickel or similar copper alloy), which has different mechanical and corrosion characteristics from AISI 316 stainless steel. Mismatched materials can cause galvanic corrosion and may not provide the required pressure containment or thread/sealing compatibility specified for LET-LOKÂ® AISI 316 tubing. - The LET-LOKÂ® product description explicitly ties allowable working pressure and fit to AISI 316 tubing dimensions and material; substituting a C762L fitting would deviate from that specification and therefore does not meet the stated compatibility requirements. If you need a certified compatible connection, use fittings made of AISI 316 specified for LET-LOKÂ® inch tubing.
