Colby Valve Permanent Metal Valve Stems Replacement Kit, Standard .453, 2-Pack — Brass, External-Install

Colby Valve Permanent Metal Valve Stems Replacement Kit is a two-pack of durable, external-install brass valve stems designed to replace standard .453 TPMS stems without removing the tire.

This replacement kit gives you a long-lasting metal valve stem option built from 360 brass and manufactured in the USA. The stems are engineered to install from the outside of the wheel, so you can swap them in quickly without demounting the tire. Their extended length helps them reach through recessed valve openings while the included gasket seals securely when tightened to the recommended torque.

How do these valve stems install without taking the tire off?

The Colby Valve stems are designed for external installation: you push the stem through the valve opening from the outside and tighten until the gasket seats. That eliminates the need to break the bead or remove the tire for most standard applications, saving time and reducing service complexity.

• Install through the valve hole from the wheel exterior in about one minute.
• Insert fully until the gasket lip sits flush on the wheel opening.
• Tighten while holding stem steady; stop if the gasket spins.

Are these compatible with recessed valve openings?

Yes — the stems are made longer than typical .453 stems to reach most deeply recessed openings. Their length and brass construction make them suitable for many wheels that otherwise require special fittings.

• Standard .453 diameter with extended length for deeper wells.
• Works with many aftermarket and OEM wheels that have recessed ports.
• Brass construction resists corrosion and maintains a reliable seal.

What are the recommended installation steps and torque?

Insert the valve fully until the gasket lip is firmly seated against the wheel. Hold the valve steady and tighten to the suggested 10–15 inch-pounds; if the gasket begins to rotate, stop tightening to avoid damaging the seal.

• Seat gasket fully before tightening.
• Recommended torque: 10–15 inch-lb for secure sealing.
• Stop if gasket spins — this indicates proper seating has been exceeded.

What materials and manufacturing details matter for longevity?

These replacement stems use 360 brass components, a material chosen for strength and corrosion resistance. Designed and patented in the USA, they are intended as permanent metal replacements for rubber or plastic stems that can deteriorate over time.

• 360 brass construction for durability and corrosion resistance.
• Patented design for external installation and secure sealing.
• Made in the USA to Colby Valve quality standards.

Who is this for: The Colby Valve Permanent Metal Valve Stems Replacement Kit is for vehicle owners, fleet managers, and tire technicians who want a reliable, long-lasting metal valve stem that installs quickly without removing the tire. It suits wheels with recessed valve openings and anyone looking to upgrade from rubber stems to a durable brass alternative made in the USA.
