RS PRO Silicone O-Ring O-Ring, 4.47mm Bore, 5/16in Outer Diameter

These O-rings from RS PRO work by filling the space between two working parts to provide an airtight seal in your industrial machinery or engines. Use them to prevent contaminants from interfering with the good working function of your equipment. The silicone rings have a wide operating temperature range, so you can use them in both extremely cold and extremely hot environments. They won't be damaged by exposure to sunlight or air, as their silicone material is resistant to weathering. The material is also highly flexible, making the O-rings long-lasting and less likely to break under pressure. These seals are supplied in convenient packs of 50, so you can create multiple seals. They're ideal for food-processing machinery and equipment, as silicone is non-toxic and poses no danger to humans. You can also use them in general engineering, automotive and aerospace applications.
