Worcester Tube - Gas Supply 87161065050

Worcester

The Worcester Gas Supply Tube (Part No. 87161065050) is a genuine OEM (Original Equipment Manufacturer) metal pipework component designed for the internal gas train of Worcester Bosch Greenstar boilers. This tube acts as the primary conduit for fuel, typically connecting the gas valve outlet to the burner manifold. Given its role in transporting combustible gas, it is manufactured to stringent safety standards with precision-engineered flared ends to ensure a perfect, gas-tight fit when used with the correct gaskets.

Key Features and Specifications
Rigid Metal Construction: Fabricated from high-grade aluminum or treated steel to withstand the vibration and thermal expansion cycles within the boiler.

Precision Flared Connections: Features factory-formed ends designed to seat perfectly against the gas valve and burner interfaces.

Genuine Worcester Bosch Part: Guaranteed to have the exact length, diameter, and bends required for the specific internal layout of Greenstar appliances, ensuring no strain is put on the gas valve.

Corrosion Resistant: Treated to prevent internal and external oxidation, ensuring the fuel path remains clear of debris over the lifetime of the boiler.

Safety Critical: A fundamental part of the combustion assembly; it must maintain a 100% gas-tight seal to prevent hazardous gas escape.

Boiler Compatibility
This gas supply tube is a common component in several generations of the Greenstar range, particularly the high-output and classic models. Compatible appliances include:

Greenstar CDi Classic (Combi & System): 25CDi, 30CDi, 35CDi, 40CDi.

Greenstar CDi Highflow: 440CDi, 550CDi.

Greenstar FS (Floor Standing): CDi Regular and System models.

Note: It is essential to check your boiler’s GC (Gas Council) number, as gas pipework can vary significantly between the "Classic" and "Compact" versions of the CDi range.

Important Safety Note: This is a safety-critical gas component. Its replacement MUST only be performed by a Gas Safe Registered engineer. After installation, a full gas tightness test (spillage test) and flue gas analysis are mandatory to ensure the appliance is operating safely and at the correct gas pressure.

Maintenance and Installation Advice
During a major repair—such as a heat exchanger replacement or gas valve upgrade—this tube must be handled with care. If the pipe becomes dented, kinked, or the flared ends are scratched, it must be replaced. Engineers should always use a new Gas Valve Gasket (87161068000) at the connection points to ensure the integrity of the seal is maintained.
