Rubber bellows securing the slide of the ProPlus 60mm overrun device for KNOTT KF/KFG overrun devices

The 341091V01 ProPlus protective gaiter is a rubber element that protects the overrun brake slider/guide from dust, dirt, and moisture . This product is designed for selected KNOTT KF and KFG overrun devices used on trailers and flatbed trailers with overrun brakes.

Its purpose is to protect the overrun brake guide (piston rod) from dust, dirt, and moisture. During braking, the piston rod moves within the mechanism – proper protection prevents contaminants from entering the lubricant, ensuring smooth and reliable operation of the braking system.

The bellows are made of a flexible, weather-resistant material, making them suitable for intensive outdoor use. Regularly replacing worn bellows helps keep the overrun brake in good working order and extends its service life.

Dimensions:

• inner diameter: 60 mm
• outer diameter: 120 mm

Product advantages:

• effective protection against dust, dirt and moisture
• supports the proper operation of the overrun brake
• flexible and weather-resistant material
• compatible with popular KNOTT models
• easy installation and replacement

Compatibility with KNOTT overrun devices:

• KF27-A / KF27-A1 / KF27-A2
• KF27-B
• KF30-A
• KF30-E
• KFG27-A
• KFG30-A

Before purchasing, it is worth checking the type of overrun device on the nameplate and comparing the dimensions of the old bellows, especially the diameters on the hitch side and on the overrun device side.
