Pup Joints

We stock 2 3/8″ to 3 1/2″ in full sets and most likely have 1″, 1 1/2″, and 2 1/16″ IJ Pup Joints at the Independence, KS plant. There are almost always some 4 1/2″ and 5 1/2″ subs available too.

We can line the pup joints in both PVC and CPVC liners.


We line and stock both carbon steel and 316 stainless steel fittings and maintain a wide variety of sizes in both types of liners in stock ready to ship. We line swages, nipples, changeover nippes, and offer packer adapter nipples as well.


Seal Tite lines the customer’s packer with either PVC or CPVC liner and provides a lined tailpiece for further protection of the packer, securing fluid resistance at every downhole connection.

Our lined packers have routinely outperformed nickel-plated and plastic coated packers.

All of the above fittings and accessories add life to your string and reduces the likelihood of pulling and servicing. Many Seal Tite customers have strings of pipe that have been in extremely corrosive environments for more than 20 years and have never been pulled. Let us do the same for you.
