The Weber Hose and Regulator provides a secure, airtight connection between your grill and tank while controlling the flow of propane to the burners. REPLACEMENT: This is a replacement for a damaged hose or regulator, NOT an adapter hose for portable grills such as the Weber Q or Traveler. Please search “Weber Adapter Hose” for those needs, part number 6501. LEAKAGE ISSUES: Leaking can also be caused by a bad connection or propane tank. To check the tank, inspect the inside of the gasket for cracks or misshaping (oval shape). You can also do a soapy water test, where you apply soapy water to the valve where the regulator connects and open the valve – bubbles will form where there is a leak. COMPATIBLE GRILLS: Weber Genesis Silver C, Gold B/C, Platinum B/C and Summit Silver/Gold/Platinum gas grills manufactured after 2002. MEASUREMENTS: Regulator is 4”, Hose length is 21” Please double check the specs and fits info to ensure that you’re choosing the best part for your grill.
