Compression unions for connecting pipe in surface installations and accessible threaded joints, brass and nickel-plated threaded fittings.
Frequently Asked Questions
- When should a compression union be used instead of a pressed joint? A compression union is suitable where the joint needs to be detachable later or where pressing tools are not available, for example in surface and accessible installations.
- What is the difference between nickel-plated and brass fittings? Nickel-plated fittings have a surface finish that increases durability and improves appearance, while brass fittings are the basic version without surface finishing - functionally they are equivalent.
- Can a compression union also be used on PE pipe? Yes, the category also includes brass compression fittings designed directly for PE pipe.
- Is additional sealing required at threaded joints? Most threaded joints use PTFE tape or hemp sealing; on some fittings the seal is built in (O-ring, flat gasket).
