Ferrule Chain

£3.00

The Ferrule Chain is a practical reference tool for workshops, service vehicles and tool stations. It contains one of each size from our full range of stainless steel ferrules, providing a quick and accurate way to identify the correct size for your hose assemblies. Ideal for anyone working with hydraulic, pneumatic or industrial hoses, the Ferrule Chain ensures that the right ferrule is ordered every time, reducing errors and downtime.
Ferrules are metal sleeves crimped or swaged onto the hose’s end fitting, securing the connection and preventing detachment under pressure. This compression process, performed using a swaging or crimping machine, creates a safe and leak-resistant seal essential in demanding applications.

Features

  • Full size range included – One of each ferrule size from 9mm to 34mm
  • Quick reference tool – Use on-site or at the bench to identify ferrule sizes instantly
  • Reduces errors – Helps ensure correct sizing before ordering
  • Ideal for workshops – Suitable for engineers, technicians and mobile hose fitters
