What's included: Air pressure regulator with integrated gauge, 1/4 NPT connector, and PTFE tape for a straightforward, leakminimized installation. Why you need it: Provides precise, stable air pressure control (0–140 PSI) to protect tools, improve performance, and reduce wasted air. The regulator lets you set and monitor pressure quickly so pneumatic tools run at the intended operating pressure. Key features and benefits: Precise pressure monitoring: Builtin gauge reads 0–140 PSI for accurate adjustments and consistent tool performance. Integrated oil/water separator: Captures moisture and oil from the air supply to prevent corrosion, clogging, and premature wear in pneumatic equipment. Durable, lightweight construction: grade plastic and aluminum alloy housing resists rust and is easy to mount or handle during setup and operation. Readytofit hardware: Supplied 1/4 NPT connector and PTFE tape simplify connection to standard 1/4' NPT compressor lines and fittings. Compatibility and function: Designed for use with standard 1/4' NPT pneumatic lines and fittings. Functions as a regulator and filter in one unit—controls pressure while removing contaminants to extend tool life and reduce maintenance. Typical applications: Workshop and garage: Regulate pressure for impact wrenches, air ratchets, and pneumatic drills to prevent overpressurizing and ensure consistent torque. Painting and finishing: Provide steady, clean air for spray guns and airbrushes to reduce blemishes caused by moisture or oil. General compressedair systems: Improve performance and longevity of nail guns, tire inflators, and other pneumatic tools by delivering filtered, regulated air. Practical advantages: Easier installation with included connector and PTFE tape. Cleaner air supply reduces downtime and service needs for downstream equipment. Compact, corrosionresistant design for reliable operation in workshop environments.
