Copper Press Adaptor Pipe Fittings

Copper press adaptors are the straightforward way to carry a compatible copper press pipe run across to a threaded connection without changing your main jointing method. This range suits jobs where you need a permanent press connection on the pipe side and a defined male or female threaded interface on the other, such as connecting into valves, appliances or existing threaded components. It is a practical choice when you want to keep the speed and flame-free installation of a press system while still matching the connection required at the end point.

The first check is to treat the adaptor as two separate connections. On the press side, match the copper pipe size and the required press profile. In this collection, the observed press profile is M Profile, so it is important to confirm your compatible pipe, jaws and tool against the manufacturer’s system rather than assuming other press profiles will fit. On the threaded side, check the exact interface in full. That means male or female form as well as thread size, because a nominal size match on its own does not confirm compatibility.

The range covers common press-to-thread combinations from 15mm up to 54mm on the copper side, with threaded options including 1/2", 3/4", 1", 1 1/4", 1 1/2" and 2" across selected products. Smaller sizes are often used where you are tying domestic pipework into valves or equipment connections, while larger sizes are more relevant where the pipe run and threaded component both need greater capacity. Male adaptors are used where the fitting needs to screw into a female threaded port. Female adaptors are used where the connected part has a male threaded end.

Installation access matters with adaptors more than many straight fittings because you may need room for both the press tool and a spanner on the threaded side. The press joint is made by preparing the copper pipe correctly, inserting it to the specified depth and pressing with compatible tooling. Once pressed, that side is permanent and would need cutting out if removed later, while the threaded side may remain serviceable if the connected item allows it. Any thread sealing method should follow the adaptor and equipment instructions for that connection.

If you are building out the rest of the same system, it can help to compare the wider Copper Press Pipe Fittings range for matching couplings, elbows and tees. Once you have confirmed the press-side size, M Profile requirement and the exact thread details on the other side, choosing the right adaptor becomes much more straightforward.
