Frequently Asked Questions
What is this fitting used for?
It is used to transition from a 3/4" female BSP threaded connection (typically on a valve, manifold, or appliance) to a 15mm push-fit pipe run — a common requirement when connecting isolation valves, tap connectors, and appliance inlets.
Do I need PTFE tape on the threaded end?
Yes — apply PTFE tape to the male fitting or valve thread before connecting the 3/4" female end to ensure a watertight seal on the threaded side.
Is the push-fit end removable?
Instantor push-fit fittings are generally demountable using a push-fit release tool. Check the product specification for your specific fitting.
What pipe is compatible with the 1/2" push-fit end?
Compatible with 15mm copper tube and most push-fit compatible plastic pipe (PEX, PB, CPVC).
Is it suitable for hot water?
Yes — rated for hot and cold water supply within standard domestic temperature and pressure limits.
Lead-free brass body with EPDM seal and stainless steel grab ring (push-fit end).
