Dual Bead Super Sealing
300 Series Stainless Steel Inner Liner
This is an excellent constant tension
clamp for air-to-air and coolant
applications. The unique “Dual Bead
Shield” inner liner provides spring
action and concentrates band-sealing
pressure, providing 30% more sealing
performance than standard smooth liner
clamps. Flanged edges protect soft hose
compounds. This clamp can be found
in the marine, agriculture, construction
and off-highway markets.
