Weber Hose and Regulator Kit — 30-inch Hose & 4-inch Regulator for Genesis 300 and Summit 400/600, 2-Year Warranty

The Weber Hose and Regulator Kit provides a secure, airtight propane connection and steady fuel flow to restore safe, consistent heat for compatible Weber gas grills.

Designed as a direct replacement component, this kit combines a 30-inch flexible hose with a 4-inch regulator to control liquid propane delivery from a tank to the grill burners. It’s intended to replace worn or damaged lines on certain Weber Genesis and Summit models and helps maintain even cooking performance when installed and tested correctly.

How does this kit improve grill performance?

Replacing a faulty hose or regulator can eliminate leaks, pressure fluctuations, and inconsistent burner flames. With proper fitment and a functioning regulator, propane is delivered at the intended pressure for stable, uniform heat across the cooking surface.

• Regulates liquid propane for steady heat distribution.
• 30" hose length gives flexible placement between tank and grill.
• 4" regulator size built to match Weber grill requirements.
• Helps prevent pressure drops that cause uneven cooking.

Will this part fit my Weber grill model?

This replacement is compatible with Genesis 300 series grills that have the front-mounted control panel and with Summit 400 and 600 series gas grills. It is not an adapter hose for portable Weber Q or Traveler models; those require the separate adapter hose (part number 6501).

• Compatible: Genesis 300 series (front control panel).
• Compatible: Summit 400 and 600 series gas grills.
• Not compatible: portable Weber Q/Traveler grills (use adapter hose 6501).
• Always verify model and serial info before purchase.

How do I install and check the hose and regulator for leaks?

Installation generally involves disconnecting the old hose at the tank and regulator ends, fitting the replacement, and tightening connections per manufacturer instructions. After installation, perform a soapy-water leak test and visually inspect the tank gasket to ensure a safe, airtight seal.

• Turn off all burners and disconnect the tank before replacing the hose.
• Tighten fittings securely, but avoid over-torquing plastic components.
• Soapy water test: apply to connections, open valve, watch for bubbles.
• Check tank gasket for cracks or deformation (oval shape indicates replacement needed).

What are the kit dimensions and warranty details?

The hose measures 30 inches for flexible routing; the regulator body measures approximately 4 inches. Weber backs this replacement part with a 2-year limited warranty—review the warranty terms and fitment details to ensure compatibility and coverage.

• Hose length: 30 inches for typical grill-to-tank spacing.
• Regulator size: about 4 inches in overall length.
• Warranty: 2-year limited warranty from Weber.
• Check specs and fit guide before ordering to confirm fit.

Who is this for: This Weber Hose and Regulator Kit is for grill owners who need a direct replacement for a damaged or aging propane hose and regulator on specific Weber Genesis and Summit gas grills. If you have a portable Q or Traveler grill, need an adapter hose, or are unsure about fit, verify your model or consult Weber parts resources before purchasing. Proper installation and leak testing will restore safe operation and more consistent cooking performance.
