The EXCAL teat intake elbow is supplied plain or with stop valve. 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.
