Williams Comfort Products 6CN100T06 Lock-nut Cylinder

Product Description

The WILLIAMS COMFORT PRODUCTS 6CN100T06 is a 6-inch straight lock-nut cylinder designed for use in gas heating and venting applications. This fitting provides a secure, mechanically locked connection point within a vent or flue assembly, helping maintain alignment and gas-tight integrity at the joint. The straight configuration suits direct runs without offset, and the lock-nut design eliminates the need for additional fastening hardware at the connection point. HVAC and heating technicians install this component as part of a larger venting system assembly on gas-fired appliances.

This cylinder is suited for residential and light-commercial gas heating installations where a 6-inch straight vent section with a lock-nut connection is required. It is typically installed in B-vent or direct-vent flue systems on gas furnaces, wall heaters, or similar appliances that use this connection standard. Installers working on Williams Comfort Products heating equipment will encounter this fitting as an OEM-style venting component in those systems.

• 6-inch straight configuration for direct vent-run installations
• Lock-nut connection design for secure, tool-assisted joint assembly
• Sold individually (each), with a minimum order quantity of 1

Compatibility

Installation Notes

Installation should be performed by a licensed HVAC technician or gas-appliance service professional. Shut off gas supply and allow the appliance to cool completely before disassembling any venting components. Follow local codes and manufacturer venting guidelines, including applicable IFGC requirements, when assembling or replacing flue and vent sections. Ensure all lock-nut joints are fully seated and secured before restoring gas supply and firing the appliance.
