Selecting and maintaining swaging tools

19 March, 2025

Selecting the right swaging tool

1. Match the tool to the application – Ensure the swaging tool is compatible with the material and size of the hose or tubing. Manual tools work well for small-diameter, low-pressure applications, while hydraulic or pneumatic swaging machines are necessary for heavy-duty operations.

2. Consider precision and adjustability – Look for tools with adjustable settings to accommodate different fitting specifications. Precision is key to avoiding under- or over-swaging, both of which can compromise system integrity.

3. Check for manufacturer compatibility – Always use tools recommended by the fitting or hose manufacturer. Mixing components from different brands can lead to improper swaging and potential failures.

4. Prioritise portability and ease of use – If on-site work is required, opt for compact, lightweight tools that still provide the necessary force. Cordless or battery-powered swaging tools can improve efficiency in remote locations.

Essential maintenance tips

1. Regular calibration – Periodically calibrate swaging tools to maintain accuracy. Deviations in force application can weaken fittings and lead to premature failure.

2. Clean after each use – Remove debris, dust, and oil from swaging dies and moving parts. Contaminants can affect precision and wear down components.

3. Inspect for wear and damage – Check for worn-out dies, cracked handles, or hydraulic leaks. Replace damaged parts immediately to avoid performance issues.

4. Store properly – Keep tools in a dry, dust-free environment. Moisture and dirt can corrode metal parts, affecting longevity and reliability.

By selecting the right tool and following a strict maintenance routine engineers can ensure durable, highperformance swaged connections every time.
