Hose Loops are mainly used for transporting fluid in high pressure discharge line, well testing line and cementing slurry line. Jereh Hose Loops include long radius type and flexible type. Long radius type combines long radius swivel joint and integral pup joint, featuring high erosion resistance, less vibration, impact resistance and large flow. Flexible type has single union connection, featuring excellent seal and rotary performance. Jereh Hose Loops are available in both standard service and H₂S service, applicable to cementing, fracturing, acidizing and testing lines. Customized design is also available to meet various demand.

Check Valves are widely used in high pressure lines to control one-way flow and prevent fluid from flowing back to the pump, thus to protect pipeline safety. Jereh Check Valves include top-entry check valves, in-line flapper check valves and dart check valves. Flappers of top-entry and in-line flapper check valves which are mainly used in fluid condition adopt complete coating design, increasing service life. Dart check valves are mainly used in air condition.

Jereh swivel joints are forged from premium alloy steel, handled with advanced metal melting and heat treatment technology to ensure strength and hardness. Based on analysis of weight, resistance to abrasion and blasting, Jereh developed optimum wall thickness for swivel joints, introduced advanced equipment and machining technology to ensure the uniformity of wall thickness, the longest service life and highest safety factor with the weight unchanged. Special seal design and seal material significantly increase sealing capability and service life.

Safety Valves act as a fail-safe for reciprocating plunger pump, pressure vessel and testing lines, etc. The open/close pressure is controlled by spring washer. When the pressure exceeds preset limit, the valve may automatically unload. When the pressure drops below preset limit, the valve may automatically close to protect people and equipment. Jereh Safety Valves feature high strength, wide pressure range and stable performance. Jereh Safety Valves are forged from premium alloy steel, handled by advanced metal melting and heat treatment technology. Different number combination of spring washers allows wider pressure adjustment range. Pressure relief device realizes stable seal. To meet various demand, Jereh has developed many types suitable for cementing, acidizing, fracturing and testing lines. Customized service is also available.
