Frequently Asked Questions
- What tools do I need to install this fitting? Press fittings require specialized pressing tongs with the correct jaw type (commonly labeled B, F, or TH depending on the system) matching the size and type of the fitting - without the proper tool, the joint cannot be made or checked.
- How do I know the joint has been pressed correctly? Quality press fittings have a press indicator (e.g. a sealing O-ring that leaks if pressing is incomplete) - a pressure test of the entire system should always be performed before it is embedded in a wall or screed.
- Can the joint be disassembled after pressing? No, unlike a screwed (compression) fitting, a pressed joint is permanent and removing it requires cutting out the fitting and replacing it with a new one.
- Must the installation be carried out by a professional? Yes, pressing fittings requires professional skill and properly calibrated tools - we recommend entrusting this to a heating/plumbing installer, especially for joints that will be embedded in a wall or screed without the possibility of later inspection.
