Compression-Fitting Nuts

    Nov. 18, 2004
    A new line of stainless-steel compression-fitting nuts is said to eliminate problems of inconsistent remakes or product galling during the assembly of stainless-steel tubing systems.

    The Moly Inside! Nut's bonded coating of molybdenum disulfide acts as a barrier between the nut and fitting-body threads to prevent galling. The coating also serves as a lubricant so fittings can be installed with less torque. The nuts are for use on the A-Lok or CPI brands of Parker compression fittings. The A-Lok fittings nut is silver-plated stainless steel and the CPI fitting nut is coated overall with "moly," while the Moly Inside! Nut is coated only on the inside.
