3M™ Re-enterable PST (Pull N' Shrink Tubing) Dome Closures with gel end seal offer fast, rugged splice protection with easy re-entry. No special tools or flames are needed for installation.
The splice is enclosed in a split polypropylene dome, clamped together with a steel latch and sealed with an O-ring. An expanded rubber tube (PST) is slipped over the base of the enclosure and onto a gel sealing collar. Pulling the plastic rip cord on the PST allows it to shrink to the minimum outside diameter necessary to form a constant tight seal. The kit is available in three sizes, which accommodates splices from 25- to 900-pair and can be used in pedestal, hand hole and pole mount applications.
For encapsulated plant, three sizes are available and require 3M™ High Gel Re-enterable Encapsulant 8882 to be ordered separately.
It is suggested to use 3M™ Scotchlok™ Connectors and 3M™ MS²™/ 3M™ 710 Modules along with the 3M™ Re-enterable PST (Pull N' Shrink Tubing) Dome Closures.
