2745 SUPPORT RINGS RC SERIES

SKU: 6335

Support rings are rigid rings in the seal stack that back up the packings and keep them properly positioned and supported under pressure. Part 2745 is the support ring specified for RC series pumps, where it sits in each cylinder's seal assembly helping the packing set hold its shape against discharge pressure. A cracked or deformed support ring lets packings shift or extrude, shortening the life of a fresh reseal — which is why stack hardware is replaced along with the seals. This part is series-specific: confirm 2745 is listed for your RC series pump on the parts diagram or data plate before ordering.
