YUFUQIDA Brass Radiator Petcock 1/4" NPT Male Drain Plug — Solid Brass, Corrosion-Resistant Valve

YUFUQIDA's brass radiator petcock is a universal 1/4" NPT male-thread drain plug designed to replace worn or leaking radiator drains with a durable, serviceable brass valve.

If you need a simple, long-lasting way to drain coolant from a radiator, this compact brass petcock offers a direct replacement that fits most aluminum and metal radiator designs. Machined from brass for corrosion resistance and mechanical strength, the valve installs in a standard 1/4" NPT female port and gives you controlled flow when you need to flush or service a cooling system. It is supplied as a single unit and tested for fit and function to reduce the chance of leaks after installation.

Will this petcock fit my radiator?

This drain plug uses a 1/4" NPT male thread, which is a common plumbing size on many radiators and cooling system adapters. Check your radiator's drain port size and thread type before ordering to ensure compatibility. If your existing plug uses 1/4" NPT male or female threads, this unit is intended as a direct drop-in replacement.

• Thread size: 1/4" NPT male — match to radiator's female NPT port
• Fitment: universal for most aluminum and metal radiators
• Single-piece supply: sold as one brass petcock drain
• Inspect threads and sealing surfaces for a leak-free install

How durable and leak-resistant is the brass petcock?

Brass is chosen for its balance of corrosion resistance and mechanical resilience in coolant systems. The valve body withstands repeated use and resists common coolant additives better than many plated steels. Proper installation with correct thread sealing practice (PTFE tape or compatible sealant) helps prevent leaks.

• Material: solid brass for long-term corrosion resistance
• Precision machining reduces wobble and improves thread engagement
• Use thread sealant or tape for secure, leak-free sealing
• Manufactured and inspected to meet performance expectations

How do I install and operate the radiator drain plug?

Installation is straightforward: clean the radiator port, hand-start the thread, then tighten to a snug seating using an appropriate wrench. Avoid over-tightening which can damage the port or valve. To drain, open the valve slowly to control flow; close it fully after service to restore system integrity.

• Preparation: drain or cool the system before working on the radiator
• Start threading by hand to avoid cross-threading
• Tighten with a wrench until seated, do not over-torque
• Operate the valve slowly to control coolant flow while draining
