Water pipe nut Tefcold SpareParts TC7300010344

A water pipe nut creates a leak-proof seal where a flexible water line meets a fixed connection on refrigeration or beverage equipment. The nut threads onto the male fitting of the appliance, compressing a captive washer against the pipe end to prevent drips and pressure loss. This simple mechanical joint is standardised across professional catering installations, allowing quick replacement without tools beyond a spanner.

To fit the nut, the operator slides it over the pipe, inserts the pipe into the appliance fitting, then tightens the nut by hand until resistance is felt. A final quarter-turn with a spanner completes the seal. No sealant or tape is required; the captive washer deforms under pressure to fill any microscopic gaps. The connection remains secure under mains water pressure and can be disassembled for cleaning or service by reversing the steps.

The nut is machined from brass, a material chosen for its resistance to corrosion and its ability to withstand repeated tightening without galling. Brass also conducts heat poorly, reducing the risk of condensation forming on the fitting in chilled environments. The internal washer is typically silicone or EPDM, materials that remain flexible across the temperature range found in commercial kitchens.

This spare part fits Tefcold refrigeration and dispensing units where the manufacturer specifies the TC7300010344 article. It is listed in the plumbing and maintenance section of the Tefcold spare parts catalogue.
