Brennan KP4310 Compression Front Ferrule 1/4 in Ss

Product Description

The BRENNAN KP4310 is a stainless steel compression tube front ferrule designed for use in compression tube fittings. The front ferrule functions as the primary sealing component in a compression-style connection, biting into the tube outer diameter when the fitting is torqued to create a leak-tight joint. Manufactured from stainless steel, this ferrule offers corrosion resistance suitable for demanding fluid and gas handling applications. It is compatible with 1/4-inch outside diameter tubing and corresponds to Swagelok part number SS-403-1. Plumbers, pipefitters, and instrumentation technicians working on high-purity or corrosive-media systems commonly specify this type of fitting component.

This front ferrule is suited for residential and commercial plumbing, HVAC refrigerant piping, instrumentation tubing, and process control systems where compression-style tube connections are specified. The compression cap end connection style makes it applicable in systems requiring a secure, remakeable tube seal without welding or soldering. Sold in a package quantity of 5, it is a practical stocking item for service shops and contractors who regularly service or build compression tube assemblies on 1/4-inch OD tubing lines.

Compatibility

Designed for use with compression tube fittings accepting 1/4-inch outside diameter tubing. Cross-references to Swagelok part number SS-403-1.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or instrumentation technicians. Before servicing any compression tube connection, depressurize and isolate the line according to system lockout/tagout procedures. Hand-tighten the fitting nut before applying wrench torque; do not over-torque, as excessive force can damage the ferrule seating surface. Verify the tube end is cut square and fully deburred before assembly to ensure a proper seal.
