  • DESCRIPTION

    Single Spring Mechanical Seal 4357 | PS-4357 Equivalent

    Direct-fit G-Type replacement equal to industry standard 4357 / PS-4357. Designed to the John Crane 2100 style for reliable, leak-tight performance. Configured with an EPDM/Carbon/Silicon Carbide face combination, ideal for demanding pump applications.

    This seal is supplied with a #129 L-shaped O-ring (75 duro) for proper sleeve fit. Unlike some OEM designs that use an offset/center-mount seat O-ring, this PS-style seal uses a bottom-mount seat O-ring layout for easier installation and direct compatibility.
