Inquiry (采购产品): vents for sight glasses We have vented sight glassed in service. What we are looking for is a vent that replaces the vent with the hole with a top that can be attacked to tubing and ran back into the gearbox because of excess foaming. We have them now but can't find replacements. **** Hidden Message ***** Dave Lister 47905 Company: Tate and Lyle E-mail: david.lister@tateandlyle.com **** Hidden Message ***** david.lister@tateandlyle.com
