Quick-action fasteners

Protex quick-action Bandclamp fasteners are speeding the inspection and testing of water and air-cooled radiators and intercooler systems manufactured by AH Fabrications. AH Fabrication supplies a wide variety of fuel, oil, air and water systems to customers ranging from World Rally Championship teams to club racers. According to AH Fabrications’ proprietor, Alex Hanczarski: “Protex Bandclamps are the perfect choice for securely attaching air adapters used to pressure test radiators, oil coolers and intercoolers. They combine the benefits of a worm drive hose clip with the speed and convenience of an over-centre fastener. Bandclamps can also be adjusted quickly to accommodate a variety of adapter diameters”. AH primarily employs models from the stainless steel Protex 58 PBC-HT range, which incorporate a triangular platform for the latch to be closed against. This feature optimises the Bandclamp’s geometry during its locking action, avoiding the need for excessive operating pressure and/or the subsequent relaxation of grip as the fastener’s mechanism goes “over-centre” on small-diameter parts. Platform Bandclamps are suitable for applications from 45-195mm diameter and feature an integral safety catch to prevent inadvertent opening, even under the most severe shock or vibratory loads.
