Hot and Cold Tubes for Supplied-Air Respirators for Plant Air Lines
Adjust the temperature of the air flowing into your respirator. These tubes rapidly spin the air from your supply line to separate it into hot and cold streams. Turn a knob to control how much air from each stream flows into your respirator.

Threaded On/Off Valves for Refrigerant
- Valve Type: Ball
- For Use With: Refrigerant
- Seal Material: PTFE Plastic
- Specifications Met: NACE (National Association of Corrosion Engineers) MR0103, NACE (National Association of Corrosion Engineers) MR0175
Often used in HVAC or refrigeration systems, these valves are designed to control the flow of ammonia, nitrogen, and other harsh chemicals. To prevent accidental spills, a spring on the handle will automatically close the valve if you lose your grip. It’s also known as a deadman’s handle. The ball has a vent to relieve gas buildup when the valve is closed. Made from 316 stainless steel, these valves have excellent corrosion resistance.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

On/Off Valves with Solder-Connect Fittings for Refrigerant
- Valve Type: Ball
- For Use With: Refrigerant
- Seal Material: PTFE Plastic
- Specifications Met: UL Listed, C-UL Listed, CE Marked
Install these valves in HVAC and refrigeration systems to control CO₂. They are operated with a wrench to give you the leverage needed to manage the flow of highly pressurized gases common in refrigeration systems. Because they require a wrench, these valves can’t be opened accidentally when bumped or snagged. Solder them to metal tubing for a permanent, leak-tight connection. To monitor pressure or fluid flow, attach a gauge to the port. The port can also be used to drain and divert liquid. These valves are full port, so they do not restrict flow.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.
