CEJN’s Series 116 T-Connection is a lightweight, one-piece coupling and nipple combination for making serial connections on high-pressure hydraulic tools, such as bolt tensioners and cylinders. Replacing traditional porting blocks that can require up to 13 components with at least five different part numbers, the compact T-connection minimizes risk for leakage by reducing potential leak points. A modified seal enables the nipple valve to handle dynamic load while disconnected, without the risk of seal damage. The tested, pre-assembled connection comes ready for installation, thereby saving assembly time and costs.
