Miniature Medium-Pressure Stainless Steel Threaded Pipe Fittings
When space is at a premium choose these compact fittings. Though small in size, they have the strength to handle medium-pressure applications. Fittings are stainless steel for very good corrosion resistance.
Female x male 90° elbow adapters are also known as street elbows.
Metric, BSPP, and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. Made from fluoroelastomer, these gaskets resist chemicals, including benzene, butyl alcohol, and ethylene glycol. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Open and close these valves with the flip of the toggle switch. Commonly used for equipment testing and gas sampling, they have threads and a hex nut below the handle for installation in instrument panels.
Manual-return valves remain open or closed when the toggle is moved into position.
Spring-return valves automatically close when the toggle is released.
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.

Fast-Acting Compact Threaded On/Off Valves
Compact
Push Button
Often used in testing and sampling applications, these valves open and close with the push of a button. They’re also known as push-button valves and are designed for installation in tight spots.
Normally open valves close when the button is pushed and spring open when the button is released.
Normally closed valves open when the button is pushed and spring closed when the button is released.
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.

Threaded Precision Flow-Adjustment Valves
Also known as needle valves, these adjust flow in small increments for metering, sampling, and other applications requiring fine flow control. Turn the handle to adjust flow. All valves have metal-to-metal seats that resist temperature fluctuations.
303 stainless steel valves are more corrosion resistant than brass and steel valves.
316 stainless steel valves have the best corrosion resistance.
Valves with packing have a nut that can be tightened to compress the packing if it leaks.
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.
