Description

Overview

This caliper sensor cover rubber gasket helps restore a tight seal around the sensor cover on air disc brake calipers. It keeps water, road grime and salt away from the sensor pocket so the components last longer. Additionally, it supports reliable brake performance by protecting sensitive sensor hardware from contamination. The caliper sensor cover rubber gasket is a small part, however it can make a noticeable difference to long term caliper condition on heavy trailers and trucks.

Features

This gasket is built for service work on heavy vehicle foundation brakes where the original seal has hardened, cracked or gone missing. It offers a simple, low cost way to tidy up a caliper during pad changes or overhaul. Key features include:

• Rubber gasket profile designed to sit under the caliper sensor cover and seal the opening
• Nominal 42mm diameter that matches the sensor cover pocket on compatible calipers
• Simple push fit design so replacement can happen quickly during routine brake service
• Suitable for many heavy trailer applications where air disc brake calipers are fitted

Specifications and Materials

This gasket is manufactured from durable automotive grade rubber suitable for high temperature and road exposed environments on heavy vehicles. Nominal 42mm outer diameter allows the gasket to sit neatly in the machined recess under the sensor cover on compatible calipers. Part number: FB2946. For background on how brake components are tested against reference fluids in hydraulic and brake systems, refer to the ISO 4926 brake fluid reference standard overview

Compatibility and Fitment

This cross-reference listing means this caliper sensor cover rubber gasket is a suitable replacement for the part numbers and applications shown. Some changes in installation may be required. SB 6/7 series, SN 6/7 series, SL 7 / SM 7, ADB22X These identifiers cover common European style air disc brake calipers on heavy trailers, dollies and some rigid trucks. Additionally, technicians should always compare the removed gasket and sensor cover to this replacement before final fitting. If the old gasket looks very different in shape or size, you should double check the caliper family before completing the job.

Compliance and Safety

Correctly sealing the sensor cover helps keep moisture away from electrical and mechanical wear sensing components, which can support more reliable brake monitoring. However, the gasket does not replace any formal brake inspection or adjustment procedure. Always follow the caliper manufacturer’s service instructions and the vehicle maker’s maintenance schedule when working on foundation brakes. In addition, chock wheels, support the axle safely and depressurise relevant air circuits before removing caliper components. If there is any doubt about brake condition, you should consult a qualified heavy vehicle brake specialist.

Trailer Applications

You will typically see this caliper sensor cover rubber gasket used on air disc brake calipers fitted to semi trailers, B double sets, tankers and tipper combinations. It suits fleet maintenance environments where brakes run hard in mixed highway and regional work. Furthermore, it can be a useful spare to keep in stock for workshops that regularly service European style air disc brake systems. For example, it fits well into pad replacement kits or routine caliper reseal work where the original gasket has deteriorated.

Cross-reference and Suitability

This part cross-references to or suits the following equivalent part numbers and compatible alternatives:

These references help confirm suitability across several related caliper families used on heavy trailers and selected truck applications, while final checks against the original caliper and gasket remain essential before road use.
