Working NBR o-ring temperature range is anywhere from about -35 c to 120 c. Like NBR, Buna-N o-rings are also nitrile products. Their main purpose is to serve as a seal between structures such as pipes, tubes, in pistons, and cylinders. Turn off the cold water valve to the tap. The standard O-ring value is 70 ShA. This expansion causes blisters and ruptures on the surface of the seal. We offer FDA-approved elastomers, Teflon seals, o-rings & much more. This style of seal is sometimes less expensive to manufacture with certain materials and molding technologies (compression molding, transfer molding, injection molding), especially in low volumes. @SoronelHaetir: I think of washers as metal, with a hose washer being an exception. The fittings use the O-ring compression mechanism to seal. High-temperature sealing o-rings are, as the name implies, designed to withstand extreme heat while continuing to provide a reliable seal between two surfaces or components. For Female fittings, the measurement is taken from the inside of the threads. The cheapest gaskets can be purchased from PLN 0.39 (in words: thirty-nine groszy) per piece in retail sales. O-ring manufacture usually relies on techniques like compression, transfer or injection moulding, machining, or extrusion. This is because most sports cars in the previous years had just such a color, a color that at the same time made us aware of the vehicle brand. Over time, repeating this process will start to have an effect on the resilience and uniformity of the materials and the torus shape of the seal, and ultimately the o-ring will need swapping out for a new one if the seal is to remain tight.

O-ring kitsfrom Viton suppliers are actually made from fluorocarbon rubber, making them excellent for withstanding higher temperatures and offering stronger chemical resistance (petroleum oils, acids, silicone fluids and gases) than most basic nitrile o-rings can cope with. You can choose from the following types of rubber: NBR, FKM, FPM, EPDM, HNBR, Silikon or FFKM, and o-rings in a seamless cover, most often known as FEP o-rings. This means that with increasing pressure in the equipment where the seal is to be installed, the seal should have a higher hardness.
