Jb Industries JB8127 Plastic Air Gap Chrome

Product Description

The JB INDUSTRIES JB8127 is a chrome-finish plastic air gap designed for use in residential plumbing drain systems. An air gap is a code-required backflow prevention device that physically separates the dishwasher drain line from the sink drain, preventing contaminated water from siphoning back into the dishwasher or potable water supply. The JB8127 mounts through a standard sink deck knockout and provides a clean, finished chrome appearance at the countertop surface. Licensed plumbers and experienced DIYers install this device as part of a compliant dishwasher drain installation.

The JB8127 is suited for residential kitchen sink applications where local plumbing codes require a physical air gap for dishwasher drain discharge. It fits through a standard sink deck or countertop knockout opening and connects the dishwasher drain hose to the garbage disposer or sink drain tailpiece. The chrome finish complements standard sink hardware in residential kitchens. This air gap is appropriate for new dishwasher installations and replacements of deteriorated or non-compliant existing air gap devices.

Key Features

• Chrome finish provides a clean, finished appearance at the sink deck surface
• Plastic construction offers corrosion resistance in wet drain environments
• Designed to meet code-required backflow prevention for dishwasher drain lines
• Fits standard sink deck knockout openings for straightforward installation
• Suitable for new installations and direct replacement of existing air gap devices

Compatibility

Designed as an OEM-style replacement air gap for standard residential dishwasher drain installations requiring a deck-mounted backflow prevention device.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer familiar with IPC and local plumbing code requirements. Shut off water supply and disconnect power to the dishwasher before beginning work. The air gap mounts through a standard sink deck knockout and requires connection of the dishwasher drain hose to the inlet and a discharge hose from the outlet to the garbage disposer or drain tailpiece. Verify that local code requires or permits a deck-mounted air gap before installation, as some jurisdictions allow alternative high-loop methods.
