During milking, thin inner wall sections collapse first, causing the barrel to assume a unique oval shape. Outer walls resist collapse, permitting air to continue feeding the Evolution X vacuum chamber during pulsation. This two-stage collapse allows for fast milking at very low vacuum levels, with virtually no slip.
Evolution X entails a twist-resistant build from top to bottom with a scalloped skirt extension, locking wedges and double hackle to seal out dirt and debris. It also fits perfectly into stainless-steel 06 style shells.
