Parker BD-KP4492 Brass Compression Tube Ferrule 10pk

Product Description

The PARKER BD-KP4492 is a brass compression tube ferrule used to create leak-free, mechanically secure connections in compression-style tube fittings. The ferrule seats between the compression nut and fitting body, biting into the tubing wall as the nut is tightened to form a pressure-resistant seal. This type of ferrule is a standard consumable component in fluid and gas distribution systems across HVAC, plumbing, and instrumentation applications. Brass construction provides good corrosion resistance and reliable deformation characteristics needed for a proper compression seal. This SKU is packaged in a quantity of 10 ferrules.

Brass compression ferrules are used in residential and light commercial systems wherever compression-style tube fittings are specified. Typical applications include refrigerant line accessories, potable water supply connections, pneumatic control tubing, and instrument sensing lines. Licensed plumbers, HVAC technicians, and instrumentation mechanics install these components during new construction, system retrofits, and maintenance service calls where tubing joints must be remade.

Key Features

• Brass material provides corrosion resistance and reliable cold-working deformation for a secure bite on tubing
• Designed for use with standard compression-style tube fitting bodies and nuts
• Packaged in a quantity of 10 ferrules per package for service stock and repair kits
• Compact form factor suitable for tight-access installations

Compatibility

Designed as an OEM-style replacement ferrule for use with standard compression tube fittings where a brass ferrule of matching tube size is specified. Verify tube outside diameter and fitting series before installation.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians following applicable IPC and IFGC provisions for the system being serviced. Shut off and depressurize the fluid or gas line completely before disassembling any compression fitting. Do not reuse a previously compressed ferrule — once deformed, a ferrule should be replaced with a new one to ensure a reliable seal. Hand-tighten the compression nut before applying wrench torque per the fitting manufacturer's guidelines.
