Description
Overview:
Exhaust Bobbins 5/16" UNF Universal Fitting (Part No. 405 101) are rubber vibration isolators used to mount and steady exhaust sections and silencers on vehicles and small plant. Each bobbin uses a resilient rubber core bonded to threaded metal ends to separate the exhaust from the chassis or mounting brackets, reducing transmitted vibration and noise. The 5/16" UNF thread (major diameter approx. 7.94 mm, typically 24 TPI) suits many legacy and current exhaust fittings across cars, light commercial vehicles, generators, compressors, and garden machinery with engine-driven exhausts such as ride-on mowers. Designed for routine maintenance and repairs, they help protect welds, brackets, and pipework from fatigue by cushioning movement during operation and start-up.
Key Features:
- Universal 5/16" UNF thread for broad compatibility (approx. 7.94 mm major diameter; typically 24 TPI)
- Rubber isolator design reduces vibration transfer and exhaust boom
- Helps prevent fatigue cracks in brackets and welds by damping movement
- Durable construction with metal threaded ends for secure, repeatable tightening
- Compact bobbin profile fits tight spaces around exhaust tunnels and frames
- Straightforward replacement using standard spanners; no special tools required
- Suitable for vehicles, plant, and garden machinery with engine-driven exhausts
- Aids quieter operation by isolating exhaust resonance from the chassis
- Corrosion-resistant metal components support long service life in road grime and moisture
- Ideal as a preventative maintenance part during exhaust or bracket replacement
Typical Applications:
Securing silencers, front and rear exhaust sections, and heat-shielded brackets on cars and vans; mounting exhausts on generators, compressors, welders, pressure washers, compactors, and ride-on mowers; replacing perished or cracked mounts to restore correct exhaust alignment and reduce vibration and rattles.
Also known as:
Exhaust mount, exhaust hanger, rubber bobbin, anti-vibration mount, vibration isolator, bobbin mount, exhaust rubber, isolation bobbin.
