American Granby 6300 1-1/4" Lead-Free Brass Check Valve

The American Granby 6300 1-1/4" lead‑free brass check valve delivers reliable poppet-style sealing for cold-water and water-well systems. Designed for long service life, it combines a lead-free brass body with a Buna‑N rubber-coated poppet and stainless steel spring hardware.

• Lead‑free brass body and poppet for corrosion resistance and potable-water safety.
• Buna‑N rubber-coated poppet provides positive sealing under high and low pressures.
• Stainless steel spring, washer and locknut ensure reliable, jam-resistant operation.
• Delrin poppet stem guide improves alignment and flow; hex ends simplify installation.
• Rated to 400 psi WOG; enters a 2-1/2" casing — designed for 1-1/4" FNPT threaded connections.
• NSF/ANSI 372 lead‑free certified; intended for cold-water and well applications.

Use the 6300 when you need a compact, tested check valve for pump and well systems where reliable backflow prevention and low maintenance are required. Inspect seals periodically and replace if worn; for installations outside cold-water service, consult the manufacturer for compatibility.
