Ketofa TR-416 Metal Tyre Valve Stems — Silver 8-Pack, Brass Chrome, 130 PSI Rated

Ketofa TR-416 metal clamp-in tire valve stems are durable brass valve stems with chrome finish sold in an eight-piece pack, engineered to replace worn or leaking stems and rated to 130 PSI.

These clamp-in valve stems are designed for drivers and mechanics who need a reliable, long-lasting sealing solution for rims with 0.453" or 0.625" valve holes. Built from brass with a chrome plating and rubber sealing components, each stem combines corrosion resistance with practical service features like a 1.5" effective length and nickel-plated high-temperature valve cores. They arrive as a set of eight to handle multiple tires or spares, and are air-tested to help ensure proper sealing before shipment.

Will these valve stems fit my wheel rims?

They are made for rims with two common hole sizes: 0.453" (about 11.5 mm) and 0.625" (about 16 mm). Confirm your rim’s valve hole diameter before purchasing to ensure compatibility. The stems have a roughly 1.7" overall length and a 1.5" effective length suitable for many standard and deeper-offset wheels.

• Fits valve holes: 0.453" and 0.625" (approx. 11.5 mm and 16 mm).
• Effective length: 1.5" to suit a variety of rim depths.
• Overall size: ~1.7" long by 0.75" wide.
• Check rim specification or measure hole before ordering.

How durable and weather-resistant are these valve stems?

Constructed from brass with a chrome-plated exterior and rubber sealing parts, these valve stems are designed to resist corrosion and normal wear from road exposure. The nickel-plated valve cores improve heat tolerance and help maintain a consistent seal under varying conditions.

• Brass body for strength and corrosion resistance.
• Chrome plating resists oxidation and maintains finish.
• Rubber seals deliver reliable pressure retention.
• Nickel-plated cores for higher temperature endurance.

How do I install TR-416 clamp-in stems and what tools are needed?

Installation is straightforward for anyone familiar with tire servicing: the clamp-in construction snaps into the rim hole and is secured with the nut, typically using a valve stem tool or a standard wrench. For a safe, leak-free fit, remove the tire from the rim or use proper tools; improper installation can damage the stem or rim.

• Requires clamp-in valve stem tool or compatible wrench for secure tightening.
• Best installed with the tire off the rim or by a professional installer.
• Includes high-temperature cores and is air-tested for sealing performance.
• Follow torque guidelines to avoid over-tightening or distortion.

How well do these hold tire pressure and are they tested?

Each valve stem is manufactured and air-tested to help ensure a dependable seal, minimizing slow leaks and pressure loss during normal use. They are rated up to 130 PSI, which covers typical passenger, light-truck, and many aftermarket wheel applications when used appropriately.

• Rated operational pressure: up to 130 PSI.
• Air leak-tested before packaging to verify sealing.
• Rubber gaskets help maintain airtight performance over time.
• Sold as an 8-piece set for multiple tires or spares.

Who is this for? Ketofa TR-416 valve stems suit car and light truck owners, fleet maintenance crews, tire shops, and DIY enthusiasts who need a robust replacement for cracked, leaking, or corroded clamp-in stems. If you require compatibility with 0.453" or 0.625" rim holes and value metal construction with sealed cores, this eight-pack offers multiple installs and spares for routine maintenance or wheel upgrades. Confirm rim hole size and follow standard installation practice or have a trained technician fit them for best results.
