Pro-Grip Connectors contain many features that make them stand out above the rest. Features, such as smooth wings on the body, allowing users to install many fittings with less stress on their hands. Large ridges on the nuts make them easier to tighten, and an advanced sealing interface provides for a positive seal. Additionally, the long tape barb helps guide the drip tape into the right position, and ensures a better seal by allowing more drip tape past the seal point.
