The orange Excal teat intake elbow is supplied with a stop valve (non-return). 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 or fatty residue. In these cases it is best to use the white non-valve elbow 214763 or remove the elbow. 

The intake elbow fits directly into the back of the teat and ensures suction from the very bottom of the bucket or feeder. The elbow should be fitted with the arrow facing the teat end. 
Valve fits 10 mm teat hole.

Supplied in 10-packs only.
