Glenlock Couplings The Glenlock and Hydrasafe Couplings systems of utility hose connectors are uniquely designed with non-interchangeable features that ensures utility hoses carrying different media cannot be mistakenly connected together. This, combined with our colour coded sleeve system ensures that HSE risks are minimised. In addition, the Hydrasun developed and manufactured Glenlock range of connectors do not damage the hose when swaged, therefore reducing assembly failures.
