Product detailed description

Reversed reduction 5/4″-1″ brass

- external / internal MF thread

• max. pressure up to 1.5 MPa
• max. temperature up to 110°C

Brass threaded reducing fitting – connects pipes or fittings with different thread sizes into a single joint. Brass is a long-proven, standard material for threaded water and heating pipework thanks to its corrosion resistance and reliable tightness when the joint is properly tightened.

Frequently asked questions

• How do I choose the correct fitting size? The thread size (e.g. 1/2", 3/4", 1") must exactly match the thread size on the pipe or fitting you are connecting to – dimensions such as FF (female-female), MF (male-female) and similar abbreviations in the name indicate the type of thread on each side of the fitting.
• What do the abbreviations FF and MF mean in the name? F (female, internal thread) and M (male, external thread) denote the type of thread on the given side of the fitting – for example, "FF" means an internal thread on both sides, "MF" an external thread on one side and an internal thread on the other.
• Is sealing material needed during installation? Yes, sealing material (e.g. PTFE tape or hemp fibre with sealing paste) is normally used on threaded joints to ensure a perfectly tight connection – the thread alone, without sealing, will not reliably seal.
• Does the installation need to be carried out by a professional? A simple threaded connection can be handled by a competent DIYer, but when working on an already functioning system (especially a gas or pressurised water/heating system) we recommend calling in a plumber, who will also check the tightness of the joint after installation.
• What material and pressure class does this fitting have? It is made of brass, suitable for standard water and heating pipework – the exact nominal pressure and temperature values (where specified for the particular product) can be found in the technical parameters above.
