Bulkhead Seals
NMCS45A sealing clamps are manufactured in halves to facilitate sealing of wiring bundles after being assembled and installed through a bulkhead. Each sealing clamp has two holes in the base and 4 holes in the side wall used to apply sealant. The proper application of sealant ensures a seal between the base and bulkhead as well as between the wiring bundle and clamp.

Elliptical Sealing Clamp: Available in 1/2" & 3/4"
Square Sealing Clamp: Available in 1-1/8" & 1-3/8"
