9.0198.00 BRASS PACKING RETAINER

SKU: 4294

The 9.0198.00 brass packing retainer is the rigid brass component that captures the high-pressure packing set in a triplex pump's seal stack, holding each packing at the correct position and compression around the plunger. Brass is chosen because it is strong enough to retain the stack under pressure pulses yet soft enough not to score the plunger. If a retainer is worn, cracked, or corroded, the packings can shift and leak even when the seals themselves are new — so retainers are routinely replaced during a full reseal. Confirm part number 9.0198.00 against your pump's parts list or data plate before ordering.
