  • DESCRIPTION

    Single Spring Mechanical Seal 361c / 2122 | PS-361 / PS-2122 Equivalent

    Equal to industry standard number 361 / PS-361 as well as PS-2122

    Shaft size: 1-1/4″ single spring mechanical seal with 1.875″ x .437″ cup seat, 1.787″ rotary OD, 1.687″ working length

    Please Note: 361C is a drop-in replacement for U.S. Seal PS-2122 ; Sta-Rite S32013 (and other comparable models), this seal features a smaller-OD rotary for a more universal fit—especially in tight housings and straight-bore/ANSI boxes. The crimped-head design enhances structural integrity and sealing force, delivering higher pressure capability and reliable, long-term performance.

    • Electro-polished 304 stainless steel metal parts

  • PHYSICAL PROPERTIES

    T-N11/N22 Seal Heads

    Our T-N11/N22 type seal heads are designed with a reduced outer diameter, making them fully compatible with ANSI seal chamber dimensions. The rotary portion of our seal is typically smaller than the stationary seat, and can fit straight box bores where many other seals cannot.

    These seals are direct replacements for industry-standard T-E / 1 heads as well as C / 21 models.

    Note: The N11/N22 seal designs max shaft size is 2.25″. For larger shafts, please refer to our other seal types.
