Press Release Summary:
Moly Inside!(TM) Nuts are made of stainless steel and help eliminate problems of inconsistent remakes during assembly of stainless steel tubing systems. Inside of each nut features bonded coating of molybdenum disulfide that serves as barrier between threads of both nut and fitting body. Coating also functions as lubricant, simplifying installation process. Nuts can be used on A-LOKÂ® or CPI(TM) compression fittings.

New Moly Inside!(TM) Nut Developed to Minimize Galling, Allow More Remakes, and Provide Uniform Appearance of Stainless Steel Tubing Systems
HUNTSVILLE, Alabama-October 1, 2002-A new line of stainless steel compression fitting nuts from the Instrumentation Connectors Division of Parker Hannifin Corporation may virtually eliminate the problems of inconsistent remakes or product galling during the assembly of stainless steel tubing systems.
The inside of each new Moly lnside!(TM) Nut features a bonded coating of molybdenum disulfide that serves as a barrier between the threads of both the nut and the fitting body in a stainless steel tubing system to help prevent galling, said D.F. Bush, Manager of Marketing for Parker ICD.
"Galling can occur when the combined forces of high torque and friction break down the protective oxide on the stainless steel threads of the compression fitting nut and body into microscopic fragments, causing the threads of the entire fitting assembly to lock together almost as if the parts had been welded," Bush noted.
The 'moly' coating also functions as a lubricant, which means the fitting can be installed with less torque in most applications, compared to fittings without this feature. "This makes the installation process simple and quick, resulting in a beneficial effect on maintenance costs," said Bush.
"Also," said Bush, "with this new nut, assembly remakes can be consistent and easy over the life of the fitting. This can minimize the troublesome and costly problems that engineers and maintenance supervisors face when fitting assemblies have been remade many times, resulting in leaks or other problems," said Bush.
"More remakes per fitting can mean fewer fittings have to be purchased," Bush observed.
The Moly Inside!(TM) Nuts can be used on either the A-LOK® or CPI(TM) brands of Parker compression fittings. The standard nut on A-LOK® fittings are silver plated, stainless steel. The standard nut on CPI(TM) fittings are coated overall with 'moly', while the Moly Inside!(TM) Nut has a 'moly' coating only on the inside. "All three nuts are highly engineered, manufactured according to high standards, and offer outstanding value to our customer," Bush noted. "People simply have to decide which product benefits they prefer when specifying the nuts, either as replacement items or as a part of an entire fitting assembly."
