Couplers - These have two threaded ends that allow two pipes or tubes to be joined, welded (steel), brazed or soldered (copper, brass etc.) together.

Crimped fittings require crimping of the hose to the fitting. You may require a crimping tool to achieve this. BSP fittings stands for British Standard Pipe where the angle of the threads is 55°. This standard includes BSPT (British Standard Pipe Taper) and BSPP (British Standard Parallel Pipe). Copper – can withstand very high temperatures. Always used for the final connections made to boilers/ furnaces for central heating. Hydraulics machines are used all across the world and there are many components used in each system. Thread types are used to help make parts easily identifiable and easy to maintain and replace. Some examples of thread standards include:

A hose fitting also referred to as a hose coupling, hosepipe fitting, or hose pipe connector, is a piece of equipment used in gardening and irrigation to connect and join hosepipes to faucets, adaptors and other equipment. Hosepipe couplings come in many forms, sizes and styles, and depending on your needs, there will be a certain hosepipe fitting suited to your hosepipe watering system. What are hosepipe fittings made of? Pipe fittings can be made in many different materials. Some materials are better for some functions than others: With the help of this guide, you can confidently navigate the world of hosepipe attachments so you can be sure you’re purchasing the right type of hose pipe connector for your gardening and irrigation needs. We have a wide range of pipe fitting accessories available. From PVC and ABS to stainless steel and brass, there is a huge selection to choose from. Our top brands include RS PRO, Legris, George Fischer and JG Speedfit. What are pipe fittings? NPT stands for National Pipe Thread where the threads are at a 60° angle. There is also NPT (National Pipe Taper) and NPS (National Pipe Straight).

Threaded fittings have screw threads on both sides of the connection. They accept connections with compatible threads and screw together for a secure connection. Not all threads provide a tight seal and may benefit from additional coatings or seals. PVC & ABS – light and non-toxic. They have more 'give' than copper therefore when water freezes and expands in the piping there is little chance of it busting. Garden hose fittings can be found in various styles and materials, with multiple names and purposes to match.Reducer - If a pipe needs to change diameter a reducer fixture connects the different sized ends together. Stainless Steel – Often used for aesthetic reasons where plumbing is exposed. More corrosion resistant than copper but more rigid.

Hydraulic fittings form part of a hydraulic system which connects hoses, pipes and tubes. There are various fittings which are used to connect the system together and help the hydraulic fluid to flow through. Hydraulic fittings, or hose fittings, are used to connect hydraulic hoses and pipes to other components such as valves and pumps. Compression fittings provide water tight connections by using pressure to seal the connection. They usually use a compression nut which, when tightened, removes space between the ferrule and the pipe. Pipe fittings help the flow of liquids or gas. They are used to connect systems of straight pieces of pipe and can change the direction of flow. Fittings can also assist flow through diameter changes between sections of piping. There are many different types of fittings and these can all be made out of different materials. Common Types of pipe fittings Iron – Malleable (ductile) iron is a good choice in industry because it is stronger than copper and plastic but it is rarely used in domestic installations.Elbow - These fittings are installed between two pipes to create a change of direction. They have either a 90 or 45 degree bend in the centre. PEX – Cross-linked high-density polyethylene (PEX) is ductile and tough and works well in very low temperatures. When installing be aware that it can expand drastically and it needs to be shielded when used outdoors because it is susceptible to UV. Hydraulic fittings will usually have a male and/or female connection which join to other components. The connections are usually threaded and there are several thread standards available, such as JIC, BSP and BSPP. BSP male threads will seal with BSP female threads, for example. Popular materials include plastic, brass and stainless steel fittings. Types of hydraulic fittings:
