John Guest CI-3208U7-S trap 1/4 in tube 7/16 in pipe 150 psi pack 10

Faucet Adapter for 1/4 in Tubing

This John Guest CI-3208U7-S adapter connects 1/4 inch tubing to a 7/16 inch male pipe thread. The acetal copolymer body is gray and rated for 150 psi maximum pressure. It meets NSF-51, NSF-61 and FDA standards for food and drinking water contact. The pack contains ten fittings for multi-point installations.

Check Thread Size and Media Temperature

Verify that your existing port accepts a 7/16 inch male NPT connection before ordering. Confirm the system pressure stays at or below 150 psi during operation. Ensure the media temperature remains between 33 and 140 degrees F for water or between -14 and 167 degrees F for air. The acetal copolymer material must be compatible with the specific fluids used in your application.

Ten-Pack Simplifies Multi-Fixture Jobs

The ten-piece quantity lets you equip several faucets or distribution points without opening multiple packages. Each fitting carries the same NSF and FDA certifications, so every connection meets the same potable-water standard. Having spares on hand reduces downtime if a fitting is damaged during installation or routine maintenance.
