Hose & Ducting Joiners

Hose & Ducting Joiners are designed for seamless integration with Silicone Hose UK's premium range of hoses and ducting solutions. This collection features high-performance joiners crafted from durable aluminium and lightweight plastic, catering to a variety of demanding applications.

The aluminium joiners deliver exceptional strength and resistance to corrosion, making them ideal for high-pressure and high-temperature environments. For flexibility and cost-efficiency, our plastic joiners provide a reliable solution for less extreme conditions, without compromising quality or durability.

Whether you're working on fuel lines, cooling systems, or exhaust connections, our joiners ensure a precise, secure fit and dependable performance. Explore this collection to find the perfect connector for your needs, engineered to meet the same rigorous standards as our silicone hoses.

What joiners do you stock?
Aluminium beaded and unbeaded straight joiners and an off-cut tube box; plastic barbed straight, reducing and 45 and 90 degree joiners; a corrugated pond hose joiner; and male and reducing connectors for polyurethane ducting in 50mm to 200mm outside diameter.

How do I choose between metal and plastic?
Metal for anything pressurised, hot, or in an engine bay - it holds the bore round and takes the clamping load. Plastic for low-pressure water, ducting and pond work where cost matters and there is no heat. Plastic will not corrode, which is an advantage outdoors, but it has neither the temperature range nor the strength.

How do I size a joiner?
Metal joiners are ordered by outside diameter, matched to the internal diameter of the hose sliding over them. Plastic barbed joiners are the same principle - match the barb OD to the hose bore. It should be a firm push fit; warming the hose end in hot water helps on larger sizes.

Do I need a clip on a barbed joiner?
On anything pressurised, or anything that matters if it comes off, yes. The barb resists pull-off but does not seal on its own once the hose relaxes with age and temperature. A stainless clip is cheap insurance - especially on a pond or ducting connection where a failure makes a mess.

What is the pond hose joiner for?
Joining corrugated pond hose, which a smooth barb grips poorly because of the corrugations. It is shaped to engage the corrugated profile properly. Use a stainless clip each side - a pond hose that works loose can empty a pond, which costs far more than the fitting.

How do I join two different sizes?
Use a reducing joiner rather than stretching one hose over an oversized barb, which gives an uneven seal and a joint that creeps. We do plastic straight reducing joiners, plastic 45 and 90 degree reducing joiners, and reducing PU ducting connectors covering 20 size pairings from 65mm to 50mm up to 200mm to 150mm.
