Parker BD-KP4429 Compression Tube Nut Stainless Steel

Product Description

The PARKER BD-KP4429 is a stainless steel compression tube nut designed to secure tubing connections in compression-style fittings. Compression tube nuts create a leak-resistant mechanical seal when tightened onto a compression fitting body, holding the ferrule in place against the tubing. This type of nut is commonly found in fluid and gas handling systems across HVAC, plumbing, and industrial applications. Licensed plumbers, HVAC technicians, and pipefitters install these as part of compression fitting assemblies where a removable, reliable tube connection is required. The stainless steel construction provides corrosion resistance suitable for both wet and dry service environments.

Compression tube nuts are used wherever compression fittings are specified in residential and commercial systems. Typical applications include refrigerant line connections, instrument tubing, hydraulic lines, and potable water distribution where compression-style end connections are called out. This part ships in a package quantity of two, making it convenient for jobs requiring a matched pair of nuts or providing a spare for future service calls.

• Lightweight at 0.01 pounds per package

Compatibility

Designed as an OEM-style replacement or service component for compression tube fitting assemblies requiring a stainless steel nut with compression end connections.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or pipefitters working with compression-style tube fittings. Shut off and depressurize the fluid or gas line before disassembling any compression fitting. Use appropriately sized wrenches to tighten the nut onto the fitting body without over-torquing, as over-tightening can deform the ferrule or damage the tubing. Follow applicable codes such as the IPC or IFGC depending on the service application.
