## Long description

Radiator gasket Onnline C-692122, 5/4 inch is a replacement sealing element designed for radiator connections with a 5/4-inch interface. It restores and maintains a watertight joint between mating parts in heating and cooling systems, helping prevent drips and leaks where a damaged or worn gasket would otherwise allow fluid escape. The gasket is intended for straightforward installation during routine maintenance or repair of radiators and related pipework.
Advantages
The gasket provides a tight mechanical seal at a 5/4-inch connection, reducing the need for repeated retightening. Made to fit standard radiator fittings with the specified dimension, it facilitates quicker repairs and minimizes system downtime. Its simple form factor makes handling and placement during assembly easy, and it helps maintain system pressure integrity when installed correctly.
Suitable for
 Replacing worn or damaged seals in radiator connections
 Routine maintenance of domestic and commercial heating systems
 Leak repair on cooling and hot-water radiator joints
 Use in plumbing tasks that require a 5/4-inch gasket
Key specifications
 Connection size: 5/4 inch
 Function: sealing gasket for radiator connections
 Typical application: heating and cooling radiator joints
 Form factor: flat/washer-style gasket suitable for threaded or flanged radiator fittings
How to use
Shut off the system and drain the relevant section of the radiator to a safe level before beginning work. Remove the old gasket by loosening the connection and inspecting mating surfaces for damage or deposits; clean the surfaces thoroughly. Position the replacement radiator gasket on the fitting so that it sits evenly against the mating face, then reassemble and tighten the connection to the manufacturer-recommended torque or until a secure seal is achieved. Refill and pressurize the system, then check the connection for leaks.
Usage recommendations
Use the gasket with compatible 5/4-inch fittings and avoid over-tightening, which can deform the seal. Inspect mating surfaces for corrosion or debris and replace the gasket if it shows signs of wear or compression set. For long-term performance, verify system pressure and perform periodic checks after initial reassembly.
