Ndl Industries G103-2131-18 Ss Gas Connector 18 in

Product Description

The NDL Industries G103-2131-18 is a stainless steel coated flexible gas connector designed to supply natural gas or propane to residential and light commercial appliances. The connector measures 18 inches in length with a 3/8 inch outer diameter and a 1/4 inch inner diameter. End fittings are 1/2 inch MIP on one end and 3/8 inch MIP on the other, matching common appliance and shutoff valve connection sizes. The stainless steel coating provides corrosion resistance and durability in typical installation environments. Licensed plumbers and gas fitters install this type of connector as the final connection between a gas supply line and an appliance.

This connector is suited for residential and light commercial applications where a flexible, corrosion-resistant gas line is required. Common installations include connecting gas ranges, dryers, water heaters, and similar appliances to a threaded shutoff valve. The 18 inch length provides enough working slack to position appliances without stressing the connection, making it practical in kitchens, utility rooms, and mechanical spaces with limited clearance.

Key Features

• 18 inch length provides installation flexibility for typical appliance setups
• Stainless steel coating offers corrosion resistance in damp or humid environments
• 3/8 inch OD with 1/4 inch ID sizing for compatible gas flow capacity
• 1/2 inch MIP x 3/8 inch MIP end fittings match common shutoff valve and appliance inlet configurations
• Flexible construction accommodates minor positional offsets between supply and appliance connections

Compatibility

Designed as an OEM-style replacement or new-installation flexible gas connector for residential and light commercial gas appliances using 1/2 inch MIP supply-side and 3/8 inch MIP appliance-side threaded connections.

Installation Notes

Installation must be performed by a licensed plumber or qualified gas fitter in accordance with local codes and IFGC requirements. Shut off the gas supply at the meter or main shutoff valve before disconnecting or connecting any gas line. Apply thread sealant rated for gas service to all threaded connections and pressure-test the assembly with an approved leak-detection method before restoring gas flow. Do not overtighten fittings and do not use this connector in concealed or embedded applications.
