I've been using this primer & glue combo from Oatey for making PVC pipe connections for over 20 years. I've never once had a problem with this combo pack. It's the industry standard. Now, back in the day, PVC pipe was only used in irrigation and plumbing applications. These days, however, more and more people are using PVC pipe to for DIY projects and crafts of all kinds. Whatever you're using PVC pipe for, you'll want to make good glued connections.
