There are times when you need to blank off redundant connections. This could be breathers, Dump Valves, vacuum connections or carburettors. We offer two methods of blanking off pipes/hoses:

Billet aluminium Hose Blanking Plug

All of our Aluminium blanking plugs are 30mm in length with Barbed finish,
CNC machined from solid 6063 billet aluminium designed to push inside a hose and provide a strong secure seal in any silicone hose, without slipping out.

Our aluminium plugs are CNC machined for perfect fit & grip, will fit perfectly and offer a very strong connection to all brands of silicone hoses and rubber hoses of suitable diameter. and polished for nice looks !

Aluminium Elbows are ideal for joining silicone hoses together to make bespoke systems. Viper Performance Aluminium Hose Joiners are designed to fit perfectly with any universal silicone hose. Available in sizes from 15° to 180°. 

Quality is paramount with all of our products. Our mandrel bent aluminium elbows have the tightest bend radius on the market. Most of the mandrel bends are 1.2D. They come Mirror polished, which means no coating for welding and have roll beaded ends for best hose retention. Delivered to you  with a clean finish ready to use protected with bubble wrap whilst in our warehouse and during delivery.

You can see the full range of aluminium elbows here.

Special Elbows Available:

As well as our standard elbows we also have some special hard to find elbows.

Super Long 90 elbow

This elbow has super long legs. Our standard elbows have 152mm legs but if you need longer these super long elbows have 300mm legs. Find out more here.

L shape elbow

A really unique product is our L shaped elbow. With one long leg 500mm and another at the standard 150mm. Find out more here.

Our UltraFlex silicone hoses offer fantastic flexibility with incredibly tight bend radius not at all possible with any Superflex silicone hoses or standard lengths.

The hoses feature a wire spiral inside with specially convoluted sections to create an extremely flexible hose connection not possible with other hoses. They are lightweight and are hand made in silicone and reinforced with polyester fabric.  Boasting a Temperature rating of -40°c to +180°c peak.

These pipes are ideal for air intakes, cooling, water, or moderate pressure applications and larger diameters. Also very popular with industrial applications, or marine applications, power generators etc. Available in blue only and 750mm long lengths including 50mm flat section cuffs each end.

When looking at any type of hose you will come across pressure data. You may have seen the terms ‘working pressure’ and ‘burst pressure’ amongst these. So what are they and how do they differ?

The working pressure means the pressure of the pipe fittings or flanges in the working conditions range, normally called pressure range.

The burst pressure is the maximum pressure that can be applied to the pipeline components without physical damage. Burst pressure can be defined as the maximum pressure this pipe fitting can withstand before breaking.When the pressure exceeds the burst pressure,the pipe will explode.

So what are the burst pressures of silicone hoses?

We have a technical area on our website which houses tables showing the burst pressure data for all different sizes of hose. You can find it here. https://www.viperperformance.co.uk/page-burst-pressure-thickness.html

We have the worlds largest range of straight reducers with 70 size options currently available and new sizes being added all the time. 

These reducers suit just about any application and industry with the smallest diameters suitable for water connections and the bigger sizes which are great for intercoolers, air intakes or other industries just as marine.

We build all hoses with minimum 3 layers of reinforcement plus 1mm inner liner for added protection. These are the highest quality hand made hoses, lined and multi-layered with quality fabric reinforcements.

Most straight reducers are 100mm long. All diameters are internal, it is imperative you choose the correct size for your application.

See the full range of straight reducing diameters here.

We have a variety of weld on bosses available which are manufactured from machined aluminium and polished finish. Our specially machined flared seat will give you plenty of space for a clean weld and tidy job. These bosses are ideal for adding a breather into a pipe or any connections to fuel and oil tanks. All available in several sizes.

We have 3 types of Aluminium weld on bosses available to order from our website. These include:

Barded end – for push on hoses
Available in a number of Outer Diameters, and CNC machined “fish tail / barbed ” design will secure any hose very well onto the take off. Buy Now.

We have a range of very handy tools to help you with making your intercooler pipes, coolant or intake systems. These include Tube roll beading tools, pipe flaring tools or tube straighteners for your aluminium hard lines.

These tools are very well made from quality materials and built to last. Due to their craftsmanship they are ideal for the workshop, garage or car building enthusiasts.

Hose end fitting tool

Our hose end fitting tool is an absolute god send when it comes to assembling and crimping AN hose end fittings. This tool does a great job with ease in minutes. It is supplied with a number of dies / sockets to crimp and assemble braided fuel and oil lines.

AN Spanners

Our Aluminium anodised AN/JIC wrenches are specially designed to fit the swivel hose fitting nuts and for crimp style hose end fittings used for braided fuel / oil hoses. The spanners and  wrenches are sold in sets offering excellent value for money, or sold as a single piece wrench.

Tube Straightening tool

This tube straightening tool has a vice mounted billet aluminium construction designed to heavy duty and years of service. This tube straightener will easily straighten all your fuel system hard lines and brake lines. Suitable for copper or aluminium tubing.

Tube Flaring Tool

We also do a heavy duty professional tube flare devise, designed to flare tubes to a 45° flare to apply suitable fuel hose fittings onto the tube / hard pipe.

Silicone hoses are not all the same and ensuring that the hose is of high quality will determine its effectiveness and life span. All silicone hoses have an inner liner and a minimum of 3 layers of fabric reinforcement.

Our standard polyester reinforcements are perfect for any applications where temperature will not exceed 170°C. There are some applications which will require hoses to withstand high temperatures. In this case we offer different types of reinforcements.

Polyester reinforcements 170°C

Our standard fabric is made from 100% polyester which is specially designed for pressure, strength and flexibility. This reinforcement suits most engine applications. Working temperatures are from -50℃ to +170℃, peaking at +180℃ Polyester reinforced hoses are however NOT suitable for carrying oil or fuel.

Polyester is Ideal for:

• Water
• Air
• Air intakes
• Coolant
• Small amounts of oil mist

Nomex reinforcements 220°C

When you require a higher temperature rating we have another fabric option called Nomex. The pattern of this fabric is different, we use a knitted Nomex fabric. Our Nomex reinforced hoses will withstand high temperatures up to 220°C making them ideal for Turbo application, hot air, steam, water or environments where other hoses fail.

Nomex is Ideal for:

• Water
• Air
• Coolants
• Turbo boost
• High temperatures
• Higher pressures
• Small amounts of oil mist.

FLURO LINED HOSES

For hoses which will be in contact with oil we have another liner option called Fluro Liner. This is a highly specialised product which is Ideal for contact with Oils / Oil mists and fuel Filler hoses. The Working temperatures of these hoses is from -50℃ to +170℃

Fluro ideal for:

• Water
• Air
• OIL in ASTM 1 and 3 oil mists
• transfer of fuel (fuel filler hose)  (not suitable for high octane fuels)
