Flexible Bellows & Connectors
Bombay Rubber & Carbon Works
Moulded rubber and silicone bellows that absorb movement, isolate vibration and keep powders, liquids and gases flowing cleanly .
Machines move, vibrate and expand with heat . Rigid joints transmit that stress straight into pipes, hoppers and frames . A flexible bellows or connector takes it up instead, relieving strain while still passing fluid, gas or powder through .
Bombay Rubber & Carbon Works makes bellows and connectors in natural and synthetic elastomers and in silicone, with or without reinforcement . They are used to join hoppers, mixers, silos, sifters and feeders, and to shield moving parts from dust, oil and grease .
Product Range
- Silicone Bellows: Flexible covers that protect lead screws, shafts and moving cylinders from dust, oil and chemicals .
- Flexible Step Bellows: One-piece moulded bellows joining two pipes of different diameters in powder or air transfer lines .
- Weighing Bellows: Thin, highly flexible round and conical connections for weighing systems, with conductive options .
- Vibro Sifter Sleeves: Corrugated sleeves with internal grooves to fit the bead rings on sifter inlets and outlets .
- Connector Sleeves: Flexible joints for duct misalignment, anti-vibration couplings, silo outlets and material transfer .
- Depanner Cups & Suction Cups: Food-grade silicone cups used in baking lines and in vacuum pick-and-place handling .
Material Options
| Material | Best Suited For |
|---|---|
| Silicone, transparent or coloured | Pharma, food and powder transfer; hygienic duty |
| Conductive silicone, black | where static control is needed, such as Areas hazardous zones |
| EPDM | Hot water, steam and outdoor exposure |
| Nitrile (NBR) | Oils, fuels and greases |
| Natural rubber (NR) | Abrasive materials and general industrial service |
Material choice depends on temperature, media, pressure and cleanliness requirements . Tell us your conditions and we will advise .

Frequently Asked Questions
What is the difference between a bellows and a connector?
A bellows is a corrugated flexible part, often used as a cover or joint . A connector is a flexible sleeve joining two components such as a hopper and a spout . Many parts serve both roles .
Do you offer conductive bellows?
Yes, black conductive silicone is available for applications that need static dissipation .
Can you make a bellows to my sample?
Yes . Send a drawing or sample and we will match the size, shape and material .
Are your silicone bellows suitable for food and pharma?
Food-grade silicone is available . Please state the standards or approvals you require so we can confirm the right compound .
How do I choose the right bellows?
Share the connection diameters, movement expected, temperature and material being handled .
