CKAuto TR414 Tubeless Snap-In Valve Stems, Black — 100-Pack, EPDM Rubber & Brass Core

CKAuto TR414 tubeless rubber snap-in valve stems are replacement valve stems made of ozone-resistant EPDM rubber with brass cores, supplied 100 pieces per bag for standard 11.5 mm (.453") rim holes.

Keep air sealed and TPMS-compatible wheels functioning with a bulk supply of reliable TR414 valve stems. These CKAuto units combine a brass core with durable EPDM rubber, are 100% leakage tested, and are sized for the common U.S. rim hole diameter. They’re intended as direct-fit snap-in replacements for tubeless passenger and light-truck wheels that accept TR414 stems.

What does CKAuto TR414 fit and how do I know it’s the right size?

TR414 stems are made for rims with an 11.5 mm (.453") valve hole—the most common size for many passenger cars and light trucks. Confirm your rim hole diameter before ordering to ensure a secure snap-in fit and proper seating against the wheel.

• Designed for rim holes 11.5 mm (.453")
• Standard TR414 profile for tubeless passenger/light-truck wheels
• Sold in a bulk 100-piece bag for multiple repairs or shops
• Compatible with most factory and aftermarket wheels that accept TR414

How durable are these valve stems and what materials are used?

CKAuto TR414 stems use ozone-resistant EPDM rubber around a brass central core to resist cracking and weathering. The brass insert ensures reliable thread engagement and longevity while the rubber body maintains an airtight seal under normal driving conditions.

• EPDM rubber resists ozone, heat, and aging
• Brass core for durable thread connection and corrosion resistance
• 100 percent leakage tested before packing
• Black finish for a low-profile, factory look

How are these installed and what tools or steps are needed?

These are snap-in valve stems that install from inside the wheel without pressing tools for many applications; a valve stem puller or hand tool makes seating easier and more consistent. Remove the tire from the wheel if needed, push the stem through the rim hole, and pull it into place until the rubber flange seats against the wheel.

• Installation usually requires a valve stem puller or manual tug
• Best installed when the tire bead is unseated or with the wheel removed
• Confirm seating and test with soapy water or a leak tester after install
• Simple replacement for shops and DIYers familiar with tire service

What does the 100-piece bag mean for buyers and workshops?

A 100-piece bag is aimed at pros, fleet managers, or DIYers who want a ready supply for multiple tires. Buying in bulk lowers per-piece cost and keeps a dependable stock for maintenance, seasonal tire changes, or emergency replacements.

• Bulk packaging: 100 valve stems per bag
• Cost-effective for shops, fleets, and enthusiasts
• Convenient for servicing multiple vehicles without reordering
