The BRIGGS STRATTON 200280GS is a high pressure seal kit designed to restore sealing integrity in pressure washer pump assemblies. The kit provides replacement seals engineered to withstand the elevated pressures generated during operation, preventing fluid bypass and maintaining consistent output. This type of seal kit is a standard service component used by small engine technicians, outdoor power equipment service shops, and experienced DIYers performing pump rebuilds or addressing pressure loss and leakage faults. The kit measures 3.25 inches by 3.95 inches by 1.25 inches in packaged form.
This seal kit is suited for use in high pressure pump applications where original seals have worn, cracked, or failed due to extended service cycles or exposure to water and detergent. It is a direct OEM replacement component sourced from BRIGGS STRATTON, intended for use during scheduled pump maintenance or corrective service when pressure drop or external leakage is observed. Technicians typically install this kit as part of a broader pump rebuild procedure.
Designed as an OEM-style replacement seal kit for BRIGGS STRATTON high pressure pump assemblies. Refer to your equipment service manual or the BRIGGS STRATTON parts lookup using part number 200280GS to confirm fitment for your specific model.
Installation should be performed by a qualified small engine technician or pump service professional. Before beginning any pump service, disconnect the spark plug wire and relieve all system pressure by triggering the spray gun with the engine off. Refer to the applicable equipment service manual for disassembly procedures and torque sequences. Inspect all mating pump surfaces for scoring or wear before installing new seals to ensure a proper seal.
