Parker BD-KP4369 Brass Compression Tube Ferrule 10pk

Product Description

The PARKER BD-KP4369 is a brass compression tube ferrule used to create leak-resistant, mechanically secure connections in compression-style tube fittings. The ferrule seats between the compression nut and fitting body, forming a bite-style seal as the nut is tightened. This type of ferrule is a standard consumable in plumbing, HVAC, and instrumentation tubing systems. Each package contains 10 ferrules. Material is brass, which provides good corrosion resistance and machinability suited to copper, brass, and compatible soft-metal tubing applications. Licensed plumbers, HVAC technicians, and instrumentation fitters are the primary installers.

Compression ferrules like the BD-KP4369 are used in residential and light commercial plumbing, refrigeration line sets, pneumatic control tubing, and instrumentation piping wherever a compression-style tube fitting is specified. They are a replacement or service consumable — commonly consumed during disassembly and reassembly of compression joints, since ferrules deform on initial installation and should not be reused. Sold in a pack of 10 to support service calls requiring multiple connections or repairs.

Key Features

• Brass construction offers corrosion resistance and compatibility with copper and brass tubing systems
• Designed for use with standard compression-style tube fittings
• Single-use consumable — replace ferrule any time a compression joint is disassembled
• Sold in a pack of 10 to support multi-connection service work
• Compact, lightweight form factor suitable for carrying in a service parts kit

Compatibility

Designed for use with compression-style tube fittings in plumbing, HVAC, and instrumentation tubing applications where a brass ferrule is specified. Confirm tube outside diameter and fitting series compatibility before installation.

Installation Notes

Compression ferrules are installed by licensed plumbers or HVAC technicians as part of compression fitting assembly. Shut off and depressurize the line before disassembling any compression joint. Ferrules are single-use components — do not reinstall a previously compressed ferrule, as the deformed geometry will not seal reliably. Tighten compression nuts to fitting manufacturer specifications; over-tightening can crack brass ferrules or damage tubing.
