Specification Brand : uxcell BulletPoint : Mechanical Seals BulletPoint1 : [Size] - 85mm Outside Diameter, 77mm Inner Diameter, 4mm Cross-Section Diameter BulletPoint2 : [Hardness] - 70A Durometer (Shore Hardness) for resistance to penetration BulletPoint3 : [Nitrile Rubber] - Standard Nitrile Butadiene Rubber with a wide temperature range from -4℉ (-20°C) to 212℉ (100°C). The o rings has smooth surface, great oil and heat resistance, wear-resistant and good sealing performance BulletPoint4 : [Application] - These small rubber o rings are widely used for automotive, pressure washer, bathroom floor drains, filter, pump, water hose, plumbing pipe, engines, valves, air conditioning maintenance and much more BulletPoint5 : [NOTE] - Please confirm the required size and material before purchase, and put it in the right place BulletPoint6 : WARM REMINDERS: This is a non-expanding hose, not an expandable hose. It features a 100% full-length design. Due to its compact initial packaging, We recommend unrolling the hose fully when using it for the first time to prevent severe tangling. After pressurizing and straightening the hose, its flexible inner tube will easily release most of the kinks. We suggest using hose straps for neat storage to ensure convenient use in the future Color : Black ExternallyAssignedProductIdentifier : 04894878240349 ExternallyAssignedProductIdentifier1 : 700955034722 ExternallyAssignedProductIdentifier2 : 0700955034722 ExternallyAssignedProductIdentifier3 : 00700955034722 GpsrSafetyAttestation : 1 IncludedComponents : 1X Garden Hose 100 ft, 1X 10-Pattern Thumb Spray Nozzle, 1X Thread Seal Tape, 3X Sealing Rings,1X Hose Storage Straps,1X User Manual IncludedComponents1 : 1X 100ft Metal garden Hose IncludedComponents2 : 1X 10 Spray Nozzle IncludedComponents3 : 3X Leak-proof rubber gasket ItemDisplayDimensions_Length : 11.58 inches ItemDisplayWeight : 10 pounds ItemLength : 1200 inches ItemName : uxcell Nitrile Rubber O-Rings 85mm OD 77mm ID 4mm Width, Metric Sealing Gasket for Automotive Machine Plumbing, Pack of 10 ItemPackageDimensions_Height : 19.2 centimeters ItemPackageDimensions_Length : 0.8 centimeters ItemPackageDimensions_Width : 12.8 centimeters ItemPackageQuantity : 10 ItemTypeKeyword : o-ring-seals Manufacturer : uxcell Material : Nitrile Butadiene Rubber MaximumPressure : 550 pounds_per_square_inch ModelName : FH-SS02 ModelNumber : a18051600ux0249 NominalWallThickness : 0.38 inches NumberOfBoxes : 1 NumberOfItems : 100 NumberOfPieces : 10 PackageLevel : unit PartNumber : a18051600ux0249 ProductDescription :
1.They are circular in shape, round in cross-section. For use across a wide temperature range from -4℉ (-20°C) to 212℉ (100°C).
2.Nitrile has good mechanical properties when compared with other elastomers and high wear resistance. Good resistance to many petroleum oils, greases, hydraulic fluids, mineral oil and grease.
3.This O-ring is made of black nitrile rubber, has a durometer of 70A, and is designed for use in a wide variety of sealing applications.
4.O-rings commonly provide a pressure and fluid seal between cylindrically shaped, overlapping mating surfaces and are commonly seen in , faucets, flanges, valves, and various cylinders.
5.Nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight and weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.
