Type 301
The type 301 is a stationary single-cartridge seal. Thanks to its extremely short design, the type 301 is also suitable for cramped stuffing boxes with a cross-section from 7.95 mm (5/16″). The precision lost-wax casting process for the glands impresses through a high surface quality and an inexpensive sales price.
The type 301 is supplied in an O-ring design.
