Description
Product Description The Tomson Universal Thermocouple Kit is a premium-grade thermal sensor designed to act as a vital safety cutoff mechanism for gas-fired appliances. It features a high-purity copper capillary wire measuring 600mm (approximately 24 inches) in length, connected to a specialized probe tip that sits directly in an appliance’s pilot flame. As long as the flame is active, the probe generates a tiny millivolt (mV) electrical current to keep the appliance’s gas valve open. If the pilot light accidentally blows out, the sensor cools down instantly, cutting the electrical signal and shutting off the gas supply to prevent dangerous gas leaks. This universal kit includes a comprehensive selection of split nuts, adapter fittings, and thread extensions, ensuring a seamless retrofitted replacement for a vast majority of OEM parts. Key Features Universal Adaptability: Supplied with multiple threaded adapter nuts to match various gas control valve styles (including standard M8x1, M9x1, and split-nut configurations). Rapid Response Time: Highly sensitive probe tip engineered to drop its thermoelectric signal within seconds of flame failure. Heavy-Duty Copper Build: Offers exceptional heat resistance and flexibility, making it easy to route through tight appliance internal housings without kinking. Compatibility Guide Because this is a “Universal” style kit, its mechanical compatibility is determined by the physical attachment fittings and the type of appliance it serves. 1. Compatible Appliance Types & Machines This kit is engineered to replace worn-out or oxidized safety sensors in light-to-medium residential and commercial gas machines, including: Gas Hot Water Systems: Storage-tank gas water heaters and instantaneous/continuous flow gas units. Kitchen Appliances: Domestic and commercial gas cooktops, standalone stoves, ovens, and overhead griddles. Heating Units: Gas log fireplaces, space heaters, wall furnaces, and ducted heating boilers. Outdoor Equipment: Gas patio heaters and heavy-duty gas barbecues with pilot assemblies. 2. Thread & Fitting Compatibility The kit comes packed with adapter nuts designed to fit major gas valve brands. It is mechanically compatible with control valves featuring: M8 x 1 metric threads M9 x 1 metric threads 11/32″ threaded connections Coaxial / Split-nut installations (common in older gas systems) ⚠️ Installation Reminder: Before installing this part, ensure the 600mm length is sufficient to reach from your gas control valve to the burner’s pilot assembly. When bending the copper wire to fit your machine, make broad, gentle loops rather than sharp 90-degree bends to avoid damaging the internal coaxial core.
