【Extended Stem for Deeper Insertion and Safer Sealing】 wdaisy press ball valves feature an extra-long valve stem that inserts deeper into copper tubing, providing a more secure mechanical grip. This extended core design helps prevent leaks and loosening under pressure — ideal for plumbing and HVAC shut-off applications.
【Dual EPDM O-Rings for Leak-Free Performance】 Built with dual EPDM O-rings, our press ball valve offers double-layered protection against leaks. Suitable for hot and cold water systems, potable water lines, and copper press fittings, this seal design enhances long-term reliability.
【Heavy-Duty Brass Body – Heavier and More Durable - Pro Press Fitting】 Constructed with thick-wall, lead-free brass, this valve weighs more than typical models, ensuring superior strength and corrosion resistance. Trusted by pros for commercial plumbing, residential copper pipe systems, and press-to-connect installations
【Full Port with 1/4 Turn Shut-Off for Max Flow Control】 The full port design allows unrestricted water flow, reducing pressure drop. Combined with a 1/4-turn handle, it offers smooth, fast shut-off functionality — perfect for water supply valves, pipe isolation, and maintenance work.
【Certified Safe – cUPC, NSF/ANSI 61 & 372 Approved】 Our lead-free press ball valves are fully certified for potable water use and meet ASME B16.51 standards. Compatible with K, L, M type copper tubing, and designed for press-fit installation using standard tools — no solder, flame, or glue needed.
