Adapter for brake hose fitting Jonnesway AN040043N-475, interchangeable 4.75 mm

Adapter for brake hose fitting Jonnesway AN040043N-475 is an interchangeable tooling insert designed to work with compatible crimping and fitting equipment for hydraulic brake hoses with a 4.75 mm internal diameter. It is intended as a replaceable part for workshop machinery used during assembly, repair and maintenance of vehicle brake lines, helping ensure precise fits and reliable sealing between hose and fitting.

Advantages

This Jonnesway adapter provides consistent dimensional accuracy for repeated hose fittings, reducing the risk of leaks and fitting errors. Made to match industry tooling interfaces, the insert simplifies replacement and reduces downtime during maintenance. Its design supports predictable compression and alignment, which contributes to reliable hydraulic performance and safer assembly processes.

Suitable for

• Crimping and fitting hydraulic brake hoses with a 4.75 mm internal diameter
• Workshop maintenance and repair of vehicle brake lines
• Manufacturing or assembly of brake hose assemblies where interchangeable tooling is used

Key specifications

• Compatible hose internal diameter: 4.75 mm
• Function: interchangeable adapter/insert for brake hose fitting tools
• Intended use: hydraulic brake line assembly and maintenance
• Material: hardened tooling steel (typical for crimping inserts)
• Fitment type: replaceable insert designed for workshop tooling interfaces

How to use

Install the adapter into the compatible crimping or fitting tool according to the tool manufacturer's instructions, ensuring it seats correctly in the tooling holder. Position the brake hose and fitting so the hose end aligns with the adapter profile, then operate the crimping mechanism to form the connection. After assembly, inspect the crimped area visually and perform a pressure or leak test appropriate for hydraulic brake systems to confirm a secure seal.

Usage recommendations

Use only with tools and fixtures specified by the tooling manufacturer, and replace the adapter if signs of wear, deformation, or corrosion are present. Follow vehicle and brake system service procedures when assembling or testing hydraulic lines, and carry out leak and pressure checks before returning a vehicle to service.
