Where smaller components than the tubing size are to be used, reducing ferrules are available with various tube/clamp size combinations offered.

Size range Clamp end to suit 1/2″ – 2″ ASME BPE compliant fittings
Weld end to suit 3/4″ – 2″ ASME tube
Material 316L stainless steel with controlled sulphur and ferrite
Options Enhanced surface finishes and electropolishing
C22 alloy and other materials

Instrument ferrule

blue Instrument ferrules

Instrument ferrules offer a simple alternative to instrument tees, allowing diaphragm seal instruments to be used in small bore piping systems. The face of the clamp fitting is tapered to meet the tube bore thus allowing the instrument diaphragm to move freely.
