Product Notes
1050Pcs O Ring Kit
At $11.99, this 1050-piece assortment is the lower-priced way to cover common sizes for car, boat, motorcycle, faucet, pump, solenoid valve, meter, and sensor repairs. The NBR material handles temperatures from -40°F to 248°F, so it suits hot and cold environments. The plastic organizer case keeps each size in a labeled compartment, which makes finding the right ring easier when you're mid-job. The trade-off: the kit is a broad assortment, not a precise match for a specific AS568 size. If you need a particular standard O-ring in quantity, a multi-size assortment won't deliver a single-size batch with a known durometer. You'll likely use part of the assortment and may need a separate purchase for a specific size.
AS568-235 Buna 70 Duro O-Ring Set
At $20.00, this set gives you 25 identical AS568-235 Buna-N (nitrile) o-rings with a 70 durometer hardness. That makes it easy to know exactly what you're using in a hydraulic, pneumatic, industrial, automotive, fuel, or oil sealing application. Because each ring is the same standard size, you can complete a job that calls for AS568-235 without sorting through mixed sizes. The limitation is that you only get one size: if your task needs different diameters or thicknesses, this set won't cover them. It's also more expensive than the 1050-piece assortment, so you're paying for precision and repeatability rather than variety. If you need multiple AS568-235 rings for a rebuild or recurring service, this is a straightforward choice. If you're browsing for assorted seals gaskets o rings without a specific size in mind, a single-size set leaves you guessing.
Final Choice by Use Case
Choose the 1050Pcs O Ring Kit if you're doing general repairs on cars, boats, motorcycles, faucets, pumps, or solenoid valves and you want a wide size range without a high upfront cost. Choose the AS568-235 Buna Set if you know you need AS568-235 rings and want 25 identical Buna-N o-rings with a 70 durometer hardness for hydraulic, pneumatic, or industrial service.
