Sanhua sight glasses provide an immediate visual of system liquid condition. Easy to follow green and yellow color indicators alert to dry or wet conditions. When a system has a refrigerant shortage or restriction, the large sight glass allows for easy detection of bubbles. Sanhua Sight Glasses are compatible with common HCFC and HFC refrigerants and are UL approved to a maximum operating pressure of 667 psig.

Diversitech 36X48X3

A robotically welded body joint. Full-size ports for unrestricted flow. These ball valves employ the latest robotic welding technology. Every continuous welded body joint is 100% factory tested to ensure positively leak-free performance. Dual Teflon ball seals surround a polished brass or carbon steel ball at each end. A secondary seal becomes effective if foreign material scores the primary seal - even in extremely unfavorable conditions such as compressor burnout - a Superior exclusive!. WA/WAS Series Ball Valves are constructed using a forged brass body with copper tube extensions on all sizes. Mechanical internal forged stops ensure positive open or closed positions - another Superior exclusive. Full open to full close with 1/4 turn. All sizes incorporate a dual stem seal design utilizing Teflon packing compressed by an internal packing nut forming the primary seal. The unique seal cap design permits valve operation without removal of the seal cap and uses Teflon gaskets to provide a secondary seal - a third Superior exclusive! There are no synthetic O-rings. Ball internal relief port design ensures shut-off in either direction of flow - even during evacuation of the system. Full flow ports in all sizes 3/8" through 3-1/8 Inch. These ball valves are non-directional flow valves and may be installed in any position.
