PureSec Water Pressure Gauge Oil Filled Stainless-Steel 2-1/2" Dial Size Dual-Scale with 1/4" Lower Mount for RO System (0-1kg(MPa)/0-150psi) | Quiet, Durable, Accurate

• High Quality Materials: Our pressure gauge is Made of 304 stainless steel with Solid Construction for indoor and outdoor use; Our RO fittings are made from safe,non-toxic materials.They are Safety used in Reverse Osmosis System；The larger 2 1/2” size is nicer too for easier viewing.
• Specification&Compatiable with: 2.5" Dial with 1/4" Male NPT lower Mount Connection,about 0.4lb;Measurement Range:0-0.7Mpa/1Mpa/1.6Mpa;Accuracy Rate:Accuracy: +/-3-2-3%;Woking Temperature:-25° to +50°; Comes with 1/4" push to connect fittings.Works for Standard 1/4 OD RO Tubings for Water filtration System
• Easy Installation:Just Wrap some Plumbing tape around the 1/4 male connection(Without tape,it may leak),Assemble the gauge as photo show, then pop in your 1/4" tubing into each end of the Tee , and finally keep the gauge standing up right with teflon tape or zip ties. To remove, just push in the outer circle on each end and pull right out. You need to make sure the tubing is cut squared to insure no leaks.Be sure you tighten the plastic fitting connected to the gauge by an adjustable wrench
• Multi-Function: This water pressure test kit is mainly used for measuring water filter pump/holding tank pressure of whole-house reverse osmosis water filtration system.But this pressure gauge itself can be also used for compressed air system/hydraulic system/ outdoor irrigation pump in irrigation system/pool pump and filter etc,even beer pressure fermentation.
• Notes:1,The air bubble at the top of the gauge face is normal by design,the gauge is faulty if without bubble;2,No need to cut the rubber plug on the top of the meter as that will open the meter to possible infiltration of particulate contaminants and moisture, as well as allow the glycerin to leak out;

• Wrap Plumbing Tape — Wrap plumbing tape around the 1/4" male connection to prevent leaks, then assemble the gauge as shown in the photo.
• Insert Tubing — Insert 1/4" tubing into each end of the Tee, ensuring cuts are squared for a leak-proof fit.
• Secure Fittings — Tighten fittings with an adjustable wrench, keep the gauge upright, and verify no leaks before operation.
• Monitor Pressure — Check pressure regularly, especially during system startup or maintenance, to ensure optimal RO performance.
