TSI Flow Products manufactures a patented Cartridge Swivel with significant improvements over the conventional swivel. These include a cartridge style seal that prevents debris from reaching the main seals to prolong service life, supports the ball race under bending load for less friction and creates a uniform bore to reduce turbulence.

TSI Flow Products manufactures our Traditional Swivel Joints with a precision ball bearing design that allows for 360 degree rotation in one through four planes. Available in 2", 3" and 4" sizes and can handle up to 15,000 PSIG. The advanced bending and machining process creates a uniform bore throughout the entire swivel to reduce damage from erosion.

TSI Pump Truck Manifolds feature TSI Cartridge Swivel Joints with a precision ball bearing design that allows you to custom configure any combination you need. DC15 Connections are recommended as it offers significant performance over the conventional 1502 hammer union connection at critical points of the frac manifold under fatigue and bending loads.
