Bolt-On Valve Stems | Coyote Accessories

Coyote-Valve-Stems

Metal clamp-in valves can be used with virtually any wheel and are highly recommended for commercial vehicles and all track activities, as well as when vehicle speeds may exceed 130 mph. All our metal valves use a 200 psi rated core.


Coyote Quality

Coyote Bolt-On valve stems are constructed with high quality brass. All rubber components are made with 30% EPDM rubber molding. EPDM, (ethylene propylene diene monomer) is a type of synthetic rubber that exhibits resistance to hydraulic fluids, similar to the characteristics of brake fluid, and outstanding resistance to heat, ozone, and weather. All our valve stem assemblies offered are manufactured to SAE requirements.


Valve Core

Regardless of the valve type, the valve core is the fundamental sealing device and should be snugly screwed into the valve core chamber. Valve cores come in short and long lengths, with the short length being preferred for high performance applications.

Valve cores are available in both nickel-plated and brass. The nickel-plated valve core is used in aluminum valve stems of tire pressure monitoring sensors because using a standard brass valve core in an aluminum tire pressure sensor valve stem will experience galvanic corrosion and the brass valve core will eventually seize in the valve's aluminum barrel.

Brass and Nicle Valve Cores

All valve cores feature a seal attached to a movable, spring-loaded pin that allows pressurized air to pass when inflating a tire, or to allow air to escape when the pin is depressed to unseat the seal. Valve cores have a working pressure of 300 psi.  It is important to protect them from grit, sand and moisture. Grit and sand might prevent valve cores from sealing completely, and moisture can freeze in cold temperatures and defeat the seal.

 

Valve Cap

Valve Caps are available in plastic and metal. The plastic caps are fine for normal driving whereas  metal valve caps to designed to withstand the high temperatures applications. Valve caps are knurled to make it easier to tighten or loosen them, while some metal caps feature hex head designs tools are available for easier removal and installation. Valve caps use a rubber washer or o-ring to seal the valve completely.

 High-speed pressure loss and core contamination are reasons why valve caps should always be used. In the event anything disrupts the valve core's seal, the valve cap provides a backup seal that prevents air from escaping.
