The LG 6.5 ft. Drain Extension Hose Kit for Dishwashers - Gray, Model # D-DH1 features a multi-diameter, stepped rubber boot that accommodates three distinct inner diameters (I.D.): 5/8 inch, 3/4 inch, and 1 inch.
Because it is a universal fit extension kit, the rubber boots on either end are pre-molded with these three size steps. This allows you to cut the boot at the specific segment that matches your connection:.
• 5/8 inch (16mm) inner diameter is typically used to connect directly to the existing built-in drain line coming from your LG dishwasher.
• 3/4 inch (19mm) is a mid-size option for specific configurations or alternative couplers.
• 1 inch (25mm) is the largest step, commonly used when routing the extension to under-sink plumbing fittings, such as a garbage disposal inlet or a sink tailpiece branch.
The kit comes complete with 3/4-inch and 1-inch hose couplers as well as adjustable stainless steel screw clamps to secure the connection once you've cut the boot to your required size...^Ivan.
