Low Friction Insulated U-Bolt and Backing Pad For Standard Schedule Pipe 120 mm ID (suit 100 mm NB pipe) - Galvanised Protected by U.K Patent Number 2 557 288 - All Rights reserved These ubolts have been developed to enable pipes to be securely guided with a minimum of friction so safe-guarding the pipe from expansion & contraction wear due to temperature changes; whilst also reducing the noise & vibration of the pipe. They are fitted with a gap between the ubolt and the pipe enabling the pipe to expand & contract yet keeping it fully guided in position. The rubber base pad acts to reduce the noise & vibration of the pipes as they carry their fluid and it is fitted with a PTFE strip to reduce the friction and hence protects the pipe as it expands & contracts. The patented ubolt sleeve is a low friction silicone rubber which rotates around the ubolt to enable the pipe to move unrestricted but be fully guided in position on the supporting framework. These are a much cheaper and more
