It is designed for easy installation and compatibility with various systems, ensuring accurate pressure readings for your reverse osmosis water filtration and more. ## Description Why you need this Oil filled Pressure Gauge?Compared to an air filled gauge, It will be much quieter as water has a tendency to vibrate when running, as well as lasting much longer as the oil in the gauge will soak up the vibrations which can cause excessive wear on air filled gauges.Sufficient PSI is very important for the correct operation of a reverse osmosis unit. Low water pressure is a leading cause of poor RO system performance. A pressure gauge assures that proper pressure is being supplied. It will also make pressure drops apparent which can tell you that sediment and carbon blocks need to be changed.Glycerin filled pressure gauges absorb vibration and pressure spikes increasing service life. This glycerin filled pressure gauge comes with 1/4" quick connect fittings for quick easy installation in-line before the RO MembraneWhat you will receive?pressure gaugex11/4" Female thread to 1/4" quick connect adapter x 11/4" Tee Stem Plug x1 ## Features - ★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; ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07D4RJ8Z3 | | Best Sellers Rank | #39,021 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #48 in Industrial Pressure Gauges | | Brand | PureSec | | Brand Name | PureSec | | Customer Reviews | 4.4 out of 5 stars 248 Reviews | | Item Dimensions | 3.54 x 2.76 x 1.18 inches | | Item dimensions L x W x H | 3.54 x 2.76 x 1.18 inches | | Manufacturer | Jeamsworld | | Material | stainless_steel_18-8 | | Material Type | stainless_steel_18-8 | | Number of Items | 1 | | Part Number | JMC-PG | | Thread Style | Npt | | Thread Type | Npt | | UPC | 607569640977 | | Unit Count | 1 Count | ## Product Details - **Brand:** PureSec - **Material:** stainless_steel_18-8 - **Item dimensions L x W x H:** 3.54 x 2.76 x 1.18 inches - **Screen Size:** 2.75 Inches - **UPC:** 607569640977 ## Images ![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) - Image 1](https://m.media-amazon.com/images/I/51sh3sRABhL.jpg) ![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) - Image 2](https://m.media-amazon.com/images/I/51maUdjKhML.jpg) ![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) - Image 3](https://m.media-amazon.com/images/I/414XeTCJUYL.jpg) ![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) - Image 4](https://m.media-amazon.com/images/I/51+jdF1fItL.jpg) ![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) - Image 5](https://m.media-amazon.com/images/I/41We67g+pqL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - 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) - Malida 1/4 inch O.D.
