9.0222.00 BRASS RETAINER RING 15mm

SKU: 2653

The 9.0222.00 brass retainer ring is a 15 mm seal-stack component that holds the packing set captured and correctly positioned around each plunger. Brass is used here because it supports the seals without scoring the plunger, while its rigidity keeps the stack from shifting under pressure pulses. A worn or deformed retainer ring lets packings move and leak, so it is commonly replaced whenever the seals are serviced. This is a size-specific part: it is made for 15 mm plungers, and fitment should be confirmed by matching part number 9.0222.00 to your pump's parts list as well as verifying your plunger diameter.
