Tresses d’étanchéité injectable
John Crane injectable packing consists of chopped, braided packing fibers combined with a controlled blend of greases and lubricants, resulting in a superior product favored by maintenance mechanics. Its pliability makes it easy to apply. This material can be injected via a high-pressure gun or can be packed by hand. John Crane injectable packing will conform to any size stuffing box.
