Custom flexible rubber bushing for auto motorcycle pipe

A flexible rubber bushing around an automotive or motorcycle pipe can separate the pipe from a supporting feature when the assembly is designed for that arrangement. The pipe diameter and surrounding bracket define two different fits. The bushing should support or cushion the intended area without crushing the pipe or leaving an exposed edge against it.

Identify the pipe's actual duty and local temperature before choosing the rubber. A general automotive pipe description does not establish suitability for exhaust temperatures, fuel contact or pressure sealing. Any movement caused by vibration or thermal changes must be considered in the complete support layout.

Seat the bushing without trapping its wall beneath an unintended clamp edge. Check the pipe route on both sides so the support does not force a tight bend or introduce sideways loading. During maintenance, inspect for local abrasion and material changes. A replacement should preserve the original clearance and support position rather than move the pipe simply because a different wall thickness fits the bracket.

Material options

Rubber. Custom formulation and color for the intended contact conditions.

Hardness selection

Rubber: 30–90 Shore A. Check the pipe route on both sides so the support does not force a tight bend or introduce sideways loading.

Custom dimensions
