Catalogue description records
The SJ300 Seal Gland is an aftermarket replacement part for SJ300 mud pumps. As a seal gland, it compresses and retains the seal around the reciprocating rod, holding the sealing element securely in position so the joint stays contained during operation. It is supplied to match the form and fit of the original SJ300 component; the model and part number shown (P1300079AATG05-5-23) are used for identification only and do not imply original-equipment manufacture.
