Heavy-Duty Bolt Clamp (with Solid Trunnions)

Unlike a spring-loaded T-bolt clamp that comes with 2-piece trunnions, this heavy-duty hose clamp features one-piece, solid barrel trunnions for increased fracture resistance. Ideally suited to aerospace, transportation, commercial and special-purpose vehicles, agricultural, machinery manufacturing, and factory construction industries. Typical uses are for fastening and sealing vacuum and positive pressure pipelines comprising plastic or steel-lined pipe fittings.
