The Smith & Blair SB-WCC-6 is an essential 6 inch well casing casing coupling
used to connect sections of well casing, linking two joints of casing for reliable well
system service. It is made from ASTM A53, ASTM A512, or carbon steel and has a minimum yield strength of 30,000 PSI.
This places it within a broader range of well casing connection products for residential, commercial,
agricultural, and industrial well construction and repair, with common casing coupling sizes also including 5.5, 7.5, and 9.5
inches. It is made with internal threads that match the casing threads for a secure threaded connection,
making this page a quick article-style product overview of what it does. This threaded design helps
connect casing evenly during installation and drilling work. This product meets applicable AWWA C219
standards for bolted sleeve-type couplings and is designed for easy installation without special pipe end preparation.
Keep pipe ends clean before installation for best results, and check the connection after installation to verify
proper sealing. It can be installed without welding to facilitate maintenance and repairs while helping maintain system
integrity, reduce vibration-related fatigue, and support efficient well operation for homeowners, contractors, and well
system professionals who need a durable, easy-to-install casing connection.
Easy to use where it counts – Simplifies how you install secure well casing connections during drilling and setup without special end preparation
Built for durability and longevity – Durable steel construction supports reliable performance over the long term
Reduces vibration-related wear – Helps reduce stress and fatigue caused by vibration between two joints
Stronger fit across project needs – Allows slight movement and flexibility within piping systems, accommodates different sizes, and can increase wall thickness at connections by 20-30% to strengthen the joint area
Versatile for ongoing service – Suitable for repair, replacement, and new installation projects while saving time on maintenance and repairs
