HVAC Sight Glass 1/4 Sweat
This ZORO SELECT sight glass provides visual monitoring for HVAC refrigerant lines. It features a sweat fitting type with 1/4 x 1/4 connections and an overall length of 4 5/8 in. The unit uses copper fittings and plated steel construction for durability. A two-piece O-ring design helps maintain a secure seal during operation.
Replaces Obscured Line Sections
Install this glass when an existing line lacks a viewing window or when a worn sight glass clouds over. The jump is worth it whenever a technician needs direct visual confirmation of refrigerant flow or condition. It upgrades a closed pipe segment into an inspectable point without changing the line size.
Fits Copper Refrigerant Lines
The sweat fittings require brazing onto 1/4 in copper tubing during assembly. Plated steel body and copper ends integrate with standard HVAC plumbing materials. The O-ring design allows the two pieces to be joined after the fittings are secured, freeing up alignment flexibility during installation. California Proposition 65 warnings apply for cancer and reproductive harm.
