Description
The Strain Relief Boot is designed to protect beer and beverage lines by limiting the bend radius at connection points. It reduces strain on LLDPE and soft metal tubing, helping prevent kinks, cracking or long-term fatigue in high-use drinks dispense environments.
Manufactured from ultra flexible rubber, the boot slides easily over imperial sized tubing to provide added support where pipework exits fittings or connects to bar fonts, taps or dispense equipment. By controlling the bend angle, it reduces the risk of snagging or accidental damage during installation, cleaning or routine cellar activity.
This simple but effective accessory helps maintain consistent flow performance in beer, soft drink and gas lines. Suitable for potable liquids, foodstuffs and inert gases, it can also be used in air, pneumatic and vacuum applications commonly found in commercial drinks systems.
