Heavy Duty Bolt Clamp (with Double Band)
Built with two layers of steel bands, this heavy duty bolt clamp offers greater clamping force than an ordinary band clamp can deliver. Ideally suited for use on specialty vehicles and military equipment, this barrel and bolt hose clamp is typically employed to seal and fasten hoses to plastic or steel-lined plastic pipe fittings forming a leak-free vacuum or positive pressure pipeline systems.
The trunnion hose clamp owes its great fracture resistance to the two layers of steel bands. It can be opened from both sides, which allows the clamp to handle a wider range of hose diameters.
