What’s this? Colourised fashion accessories?
Well, they do look great, but no. Introducing our brand new range of Flame Retardant Anti-Vibration U-bolts
These U-bolts have a D-shaped rubber sleeve which is also grooved. Designed to absorb vibration. But the rubber is a bit special:
Advantages:
– Reduce or eliminate noise and fatigue due to vibration of pipework against the supporting structure
– Prevention of galvanic corrosion due to the contact of dissimilar metals in the presence of an electrolyte
– Prevention of wear and / or crushing of composite, thin wall or non-ferrous pipework
– Flame Retardant rubber
