Product description

This kit contains 30 high-precision 9/16 inch Delrin balls, a specialized component used in the pneumatic valves and mechanical assemblies of Snap-On and John Bean tire changers and shop equipment. Delrin, an engineering thermoplastic known as polyoxymethylene (POM), is selected for these critical roles due to its exceptional dimensional stability, high stiffness, and low friction. In tire changer air valves or mechanical pivot systems, these balls act as check valves or bearings that must maintain their perfect spherical shape and smooth surface over millions of cycles. Metal balls can corrode or cause excessive wear on seat materials, whereas Delrin provides a self-lubricating, corrosion-resistant alternative that ensures quiet and reliable operation. This 30-piece kit is an essential maintenance item for shops that rebuild their own valves or mechanical components, providing a sufficient supply to replace worn or damaged balls in multiple assemblies. Proper replacement of these components ensures that pneumatic controls remain responsive and mechanical movements stay fluid and precise.
