CKAuto TR415 Tubeless Snap-In Rubber Valve Stems - Black 50-Pack, EPDM Ozone-Resistant, Brass Core

CKAuto TR415 tubeless snap-in rubber valve stems are durable, ozone-resistant tire valves designed for standard 5/8" (16mm) rim holes, supplied as a convenient 50-piece bag for passenger cars and light trucks.

These TR415 valve stems combine an EPDM rubber body with a high-temperature brass core to resist ozone and retain air pressure. Built to fit U.S. standard tubeless wheels, they accept up to typical industry cold pressures and come threaded for common caps and gauges. The set of 50 is intended to simplify fleet maintenance, tire shops, or DIY tire servicing by offering consistent, replaceable stems that are easy to seat and test.

How do these valve stems hold air and resist aging?

The CKAuto TR415 uses ozone-resistant EPDM rubber around a high-temperature brass valve core, which together reduce permeability and delay rubber degradation from sunlight and ozone exposure. Each stem is leak-tested to help ensure airtight performance out of the bag.

• EPDM rubber resists cracking from ozone and UV exposure.
• High-temperature brass core withstands heat and repeated cap removals.
• Factory leak testing minimizes early air loss.
• Rated to typical cold PSI for passenger/light-truck tires.

Will these fit my wheels and how do I install them?

TR415 stems are designed for standard 5/8" (16mm) rim valve holes common on many U.S. passenger cars and light trucks. Their snap-in design allows quick installation with basic tools or a simple pull-in method used in most tire mounting procedures.

• Standard 0.625" (16mm) rim hole compatibility.
• Overall length ~46mm and diameter ~24mm; thread diameter about 7.5mm.
• Install by seating in the rim hole then pulling into place or using a valve-puller tool.
• Accepts standard caps and tire-pressure gauges for easy checks.

What pressure and vehicle types are appropriate for these stems?

These rubber TR415 valve stems are intended for tubeless tires on passenger cars and light trucks, supporting the industry-standard cold-pressure ranges typically found in everyday vehicles. They are not engineered for specialized high-pressure applications like commercial heavy-duty or certain aftermarket racing setups.

• Suitable for passenger cars and light trucks with tubeless rims.
• Designed for standard cold PSI ranges used in everyday driving.
• Not recommended for heavy commercial or specialty high-pressure tires.
• Use with compatible caps and gauges for accurate monitoring.

Who is this for: This 50-piece pack from CKAuto is aimed at tire shops, fleet maintenance crews, and do-it-yourselfers who want an economical supply of reliable, snap-in TR415 valve stems. If you service multiple wheels or prefer keeping spares on hand for routine tire work, these rubber stems give a consistent, ozone-resistant option that fits common tubeless rims.
