quality plastic material: light and durable; the precision thread ensures good sealing performance and suitability for longterm use. Professional design with manual flow control: the knob accurately adjusts the flow rate to control the speed of the low speed cylinder. Temperature and pressure resistant: can withstand temperatures and temperature pressures; it does not trip easily and provides a secure connection. Easy installation and quick tubing connections: release ring uses an elliptical design for easy installation and disassembly; 360degree rotation allows flexible orientation; quick tubing connections with no special tools required. Applications and use scenarios: Factory automation: precisely adjust the speed of a lowspeed pneumatic cylinder on an assembly line. Laboratory and testing setups: finetune flow rate for experiments or diagnostic rig involving heated air or fluids. Hot or pressure environments: maintain secure connections and reliable performance where temperature and pressure conditions are present.
