The Roman Seliger reusable clamp incorporates a lip, which is designed to engage behind an annular security collar on the hose stem to positively prevent hose ‘blow off’. The clamps are heavily under-ribbed to provide excellent grip, and when correctly selected and fitted, the hose is compressed between the hose stem and the clamp in a similar fashion to a swaged fitting. Roman Seliger clamps are a streamline design and the bolts sit in a recess which leaves no projections to snag or injure an operator.
