Gas

Pipestock supplies a range of gas pipework systems for domestic, commercial and light industrial installations. The range covers corrugated stainless steel tubing (CSST) from TracPipe, Gastite and Gas Flex Systems, yellow MDPE gas pipe for below-ground supply, George Fischer PRIMOFIT malleable iron fittings and a choice of gas valves. Together, they cover gas pipework from the incoming supply through to the appliance connection.

Gas installations use different pipework depending on the route, location and application. Flexible CSST suits internal and above-ground runs where fewer joints and faster routing are an advantage. Yellow MDPE is the established choice for buried gas supply pipework. Malleable iron fittings and gas valves complete the system, providing connections, isolation and control.

Products within the gas range are used across a variety of installation types, including:

• Domestic gas supply to boilers, hobs, fires and other appliances
• Commercial kitchens and catering installations
• Plant rooms and commercial heating systems
• Below-ground supply pipework from the meter to the property
• Retrofit and refurbishment projects where flexible routing reduces disruption

• TracPipe CSST: Flexible corrugated stainless steel gas tubing with a protective jacket, supplied with its own dedicated fittings for a complete gas pipework system.
• Gastite CSST: A flexible CSST gas piping system with its own fittings, used for internal and above-ground gas distribution.
• Gas Flex Systems CSST: Corrugated stainless steel gas tubing and fittings for flexible gas pipework installations, featuring specialist catering & cooker hoses.
• MDPE Gas Pipe: Yellow medium-density polyethylene pipe for below-ground gas supply, available with compatible fittings.
• George Fischer PRIMOFIT Malleable Iron Fittings: Fittings for joining and connecting gas pipework.
• Gas Valves: Isolation and control valves for gas pipework, used to isolate appliances, sections of pipework or the incoming supply.

In the UK, work on gas fittings and appliances must be carried out by a Gas Safe registered engineer, in line with the Gas Safety (Installation and Use) Regulations 1998. It is recommended that CSST systems are installed using only the fittings supplied for that system, following the manufacturer's installation guidance. Yellow MDPE gas pipe is intended for below-ground use and should be protected from prolonged exposure to sunlight. All completed installations should be tightness tested before being put into service.

• Established brands: The range includes products from recognised gas pipework manufacturers such as TracPipe, Gastite and George Fischer.
• Flexible installation options: CSST allows long continuous runs with fewer joints, reducing installation time in awkward or restricted spaces.
• Below-ground supply solutions: Yellow MDPE gas pipe offers a durable, corrosion-free option for buried supply pipework.
• Isolation and control: A choice of gas valves provides reliable isolation at appliances and throughout the system.

• What is CSST gas pipe?

  • CSST stands for corrugated stainless steel tubing. It is a flexible gas pipe supplied in coils, which can be routed around obstacles and cut to length on site, with fewer joints than rigid pipework.

• Can fittings from different CSST brands be mixed?

  • No. Each CSST system is designed for use with its own fittings, and it is recommended that tubing and fittings from different manufacturers are not combined.

• Why is MDPE gas pipe yellow?

  • Yellow is the standard colour used in the UK to identify buried gas pipework, which helps distinguish it from water pipe and other services during excavation.

• Can I install gas pipework myself?

  • No. In the UK, gas work must be carried out by a Gas Safe registered engineer.

• Are these products suitable for LPG?

  • Suitability for LPG depends on the product. Check the specification on the relevant category or product page before selecting.

Whether you are routing flexible CSST to a new appliance, laying MDPE supply pipework or specifying valves and fittings for a commercial installation, the Pipestock gas range covers each stage of the system.
