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.\u003c\/p\u003e\n\n\u003ch3\u003eWill this petcock fit my radiator?\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size: 1\/4\" NPT male — match to radiator's female NPT port\u003c\/li\u003e\n  \u003cli\u003eFitment: universal for most aluminum and metal radiators\u003c\/li\u003e\n  \u003cli\u003eSingle-piece supply: sold as one brass petcock drain\u003c\/li\u003e\n  \u003cli\u003eInspect threads and sealing surfaces for a leak-free install\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow durable and leak-resistant is the brass petcock?\u003c\/h3\u003e\n\u003cp\u003eBrass is chosen for its balance of corrosion resistance and mechanical resilience in coolant systems.
