TR416 Metal Valve Stems 25 Pack - Long Brass Stems for Trailer Tires

In this review the CKAuto TR-416 25-piece valve stem kit is evaluated for owners of steel trailer wheels and anyone who needs durable, leak-resistant metal stems. The bottom line: these stems stand out for their combination of a brass chrome body, EPDM rubber sealing, and a long 1 1/2' effective length that makes them especially useful on rims with 0.453' or 0.625' holes. The reviewer found them straightforward to fit, sturdy in appearance, and reliable under pressure thanks to the included high temperature valve cores and a 100% air leak test promise.

Key Features

• High quality brass construction: The brass and chrome finish resist corrosion and provide a rigid mounting point that outlasts standard rubber stems.
• EPDM rubber sealing: The rubber base offers aging resistance and a tight seal that helps hold pressure longer than typical rubber-only stems.
• Long 1 1/2' effective length: The longer stem makes installation on deeper or recessed rims easier and improves access for pressure checks.
• Includes high temperature valve core: Comes with valve cores rated for high temperature use, reducing the chance of failure under load or heat.
• Pressure rated and tested: Each stem is tested for air leaks and rated up to 130 PSI, offering confidence for trailer and heavy-duty wheel use.

Who It's For

These metal stems are ideal for trailer owners, agricultural and commercial vehicle users, and anyone replacing rubber stems on steel wheels where longevity and leak resistance matter. The long effective length and sturdy brass build suit wheels with deeper rims and applications where access or durability is a concern.

Shoppers who need a one-off passenger car rubber replacement or who prefer low-cost temporary fixes may want to look elsewhere; this kit is most cost-effective for those needing multiple stems or seeking a longer-lasting metal solution rather than a short-term rubber replacement.

Pros & Cons

Pros

• Solid brass and chrome finish provide corrosion resistance and a professional look.
• EPDM rubber and included high temperature cores help maintain tire pressure and prevent leaks.
• Long 1 1/2' effective length improves accessibility and fit for deeper rim holes.
• Sold in a 25-piece pack, offering strong value for fleets or multiple-axle trailers.

Cons

• Bulk pack size may be more than needed for a single passenger vehicle repair.
• Metal stems add weight and may be overkill for light everyday passenger tire use.
