Frequently Asked Questions (FAQs)
1. How do I know what crimper to use?
To determine the appropriate crimper to use, consider the wire gauge, terminal material, and crimp profile. Crimping tools are sized according to the wire gauge they can handle, typically using American Wire Gauge (AWG). Additionally, different terminals require specific crimp profiles. Taking these factors into account will help you select the right crimper for your needs.
2. Do compression fittings need to be tight?
Compression fittings should be tightened securely, but it is important not to over-tighten them. Holding the compression fitting body tightly with a pair of grips, tighten the nut with a spanner. It is generally recommended to give the nut one whole turn after hand tightening. This allows for a secure fit while avoiding distorting the olive or fitting and leaving some thread for potential adjustments or in case of a leak.
3. Do you use sealant on compression fittings?
No, it is not recommended to use sealant or tape on compression fittings. The desired seal is achieved by the mating compression components, not the threads. Using sealant or tape can hinder the ability to fully tighten the fitting and may result in failure. It is best to rely on the proper installation and compression of the components for a reliable and leak-free connection.
4. How tight do compression fittings need to be?
Compression fittings should be tightened securely but not over-tightened. It is often advised in the trade to give the nut one whole turn after hand tightening. This approach ensures a water-tight seal while leaving some thread for potential adjustments or in case of a leak. Some people also use PTFE tape around the compression fitting olive to further ensure a tight seal.
