The CAT Pumps 34262 Seal Kit is an OEM replacement set designed to service CAT 6DX and 66DX direct-drive triplex pumps, including models 66DX30G1I, 66DX35G1I, and 66DX40G1I. Each kit bundles all essential seal components—three washers (part 46730), three low-pressure seals with S‑spring (part 45188), three O-Rings for the seal case (part 13980), three V‑packing seals (part 48758), and three male adapters (part 48757)—to rebuild a single pump. Per CAT Pumps documentation, one seal kit is required per pump, and two valve kits are required per pump, making it a complete, OEM‑approved refresh for 66DX/6DX pumps.
