Parker 63NTA-8 Compression Tube Insert 1/2 Inch Od

Product Description

The PARKER 63NTA-8 is a stainless steel compression tube insert designed for use with 1/2-inch outside diameter tubing in compression fitting assemblies. This insert reinforces the tube end, preventing collapse when the compression nut and ferrule are tightened, which maintains a leak-free seal under pressure. Rated for a maximum working pressure of 150 psi and a temperature range of -40 degrees F to 200 degrees F, this insert is suited for hydraulic, pneumatic, and fluid transfer lines where reliable tube support is required. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it appropriate for applications where DOT compliance is specified.

This insert is used in compression fittings on 1/2-inch OD tubing across a range of industrial, mobile equipment, and fluid system applications. Typical installations include hydraulic brake lines, fuel lines, and pneumatic control tubing where tube wall integrity under compression is critical. It is compatible with standard compression fitting bodies and nuts designed for 1/2-inch OD tube. Plumbers, hydraulic technicians, and fluid system installers working on DOT-regulated or SAE-standard assemblies will find this insert appropriate for their service work.

Installation Notes

Installation is performed by plumbers and fluid system technicians familiar with compression fitting assembly. Before servicing any pressurized line, depressurize and drain the system fully. Insert the tube insert into the tube end before seating the tube into the compression fitting body. Follow SAE J246 and applicable DOT guidelines for assembly torque and inspection procedures.
