Parker -10756 Compression Tube Insert 1/8 in Od Brass

Product Description

The PARKER -10756 is a brass compression tube insert designed to reinforce soft or thin-walled tubing at compression fitting connections. The insert is placed inside the tubing end before the compression nut and ferrule are tightened, preventing the tubing wall from collapsing under compression load. This fitting is rated for 1/8 inch outside diameter tubing and is constructed from brass, making it suitable for use in fluid and pneumatic line assemblies found in HVAC, plumbing, and light industrial applications. Plumbers, HVAC technicians, and pipefitters install these inserts as a standard step when working with flexible or semi-rigid tubing runs.

This insert is used wherever 1/8 inch OD compression fittings are employed and tubing wall integrity is a concern. Common applications include refrigeration sensing lines, instrument air tubing, and small-bore fluid transfer lines in both residential and light commercial settings. The brass construction offers compatibility with a broad range of media including water, air, and many refrigerants. It is packaged in a quantity of 10 units per pack, making it practical for service vans and small-project restocking.

Installation Notes

This insert is installed by a plumber or HVAC technician by sliding it into the cut end of the tubing before assembling the compression nut and ferrule onto the fitting body. Ensure the tubing end is cleanly cut and deburred before inserting to allow full seating of the insert. Always depressurize and isolate the line before disassembling any compression fitting. Follow applicable IPC or IFGC guidelines for the specific system being serviced.
