Gladiator Buna O-Rings for 3/8" QC Sockets 100 Pack - 7363
Couldn't load pickup availability
This 100-pack of Gladiator Buna-N O-rings is made for 3/8" quick-connect (QC) sockets on pressure washer hoses, guns, wands, and pumps. The O-ring sits inside the socket and seals against the inserted plug, keeping the connection leak-free under pressure. Because QC O-rings are connected and disconnected constantly, they’re among the fastest-wearing parts on any pressure washer. A worn, cracked, or missing O-ring shows up as spraying or dripping at the coupler and lost pressure at the nozzle.
Made from Buna-N (nitrile) rubber, these O-rings resist water, oils, and many common cleaning solutions, and they’re rated to 250°F, making them suitable for both cold- and hot-water machines. The 100-pack is a cost-effective way to keep plenty on hand for shop counters, service trucks, and fleet maintenance, so a quick O-ring swap never holds up a job.
