Teat Intake Elbow Plain Excal 10pk Natur 
The EXCAL teat intake elbow is supplied without stop valve. There is also a valve 10-pack 211403 option available.The valve enhances suckling for newborn or weak calves, but it can be susceptible to blockage when used with some types of powder-mix milk. In these cases it is best to use the non-valve elbow (white colour). The intake elbow fits directly into the back of the teat and ensures suction from the very bottom of the bucket or feeder. Supplied in 10-packs only.
