Grommet ?28 (2 ps) De Dietrich S101089

The grommet ?28 is a rubber or plastic bushing with an inner diameter of 28 mm, used to protect and seal cables or pipes passing through panels in boilers and burners. This simple yet important component prevents chafing, vibration damage, and ingress of dirt or moisture, extending the life of wiring and tubing. In heating equipment, grommets are commonly found where control panel cords, ignition cables, or gas hoses enter the chassis. Replacing a worn or missing grommet is a quick fix during boiler maintenance that enhances safety and reliability. This durable grommet is a practical spare part for any heating system repair.
