1" DYN-O-SEAL Union For Gobi CollectorsWrite a review

This item is required to connect your Gobi collectors to your system. They should be included with the collector. The provided O-rings were the wrong size cross section. I used the O-rings that came with the collectors for a sample and had to purchase additional O-rings. A definite oversight by the Heliodyne. As expensive as they are they could at least provide the correct parts.
