Sight Glass Tri-Clamp 4"

A Tri-Clamp sight glass with borosilicate glass tube, with 4" Tri-Clamp end pieces (97.4 mm ID). This is a high quality sight glass with spacer rods between the two flanges for a perfect fit when reassembling. 

• Inner diameter Tri-Clamp 97.4 mm
• Outer diameter 160 mm
• Length 171 mm
• Tri-Clamp size: 119 mm = 4"

I recommend using the 4" (97.4 mm ID) Tri-Clamp gasket for this sight glass.
