Each kit includes everything required for installation — core housing, hex nut, washer, chrome cap with O-ring — and fits standard 5\/8\" valve holes commonly found on tractors, graders, backhoes and excavators.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these valve stems stand up to harsh farm and industrial environments?\u003c\/h3\u003e\n\u003cp\u003eThe TR618A stems are made from industrial-grade brass and EPDM rubber, giving them strong resistance to rust, corrosion and high temperatures up to 212°F (100°C).
