Value for money, good quality and fast delivery. Would definitely recommend. Review: Perfect for log splitter - a vital safety item - Installed this on a 30-ton log splitter I bought used. By running it at half throttle for light work I see considerable fuel savings, but this necessitates adjusting the 2 stage pump bypass pressure to avoid stalling the motor. One should not play around with hydraulics settings without having some way to tell if the operating pressures are safe for both machinery and operator. Gauge is smooth yet responds instantly. Needle does not dance or vibrate. I wish they had a rubber armored version, but absent that I'd say this gauge does the job perfectly. ## Features - ASME B40.1 Grade A Accuracy (+/-2-1-2%): Professionally manufactured for reliable performance; large 2-1/2" (63mm) dial with high-contrast markings ensures easy pressure reading. - Liquid Filled for Stable Reading: Glycerin filling stabilizes pointer movement and dampens vibration and pulsation to prevent needle flutter and pressure spikes, ensuring accurate dual-scale PSI/Bar readings. - Industrial & Commercial Use: Ideal for air, oil, water, and gas systems including pumps, compressors, hydraulic presses, pneumatic equipment, irrigation, HVAC, pool filtration, and general machinery. - Heavy Duty Construction: Rust-resistant 304 stainless steel case with durable brass wetted parts and copper alloy internals; chrome-plated brass connection and polycarbonate lens for impact resistance. - Standard 1/4" NPT Lower Connection: Ensures compatibility with most regulators, tanks, manifolds, and fittings. Please verify your connection size before ordering. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FBKM9SS | | Brand | CARBO INSTRUMENTS | | Brand Name | CARBO INSTRUMENTS | | Customer Reviews | 4.4 out of 5 stars 101 Reviews | | Item Dimensions | 4.41 x 3.74 x 1.3 inches | | Item Weight | 5.76 ounces | | Item dimensions L x W x H | 4.41 x 3.74 x 1.3 inches | | Manufacturer | CARBO USA | | Material | Brass and Copper alloy Wetted Parts | | Material Type | Brass and Copper alloy Wetted Parts | | Model | L25-SSL-4.0K | | Number of Items | 1 | | Part Number | L25-SSL-4.0K | | Thread Style | 1/4" Npt | | Thread Type | 1/4" Npt | | UPC | 810017351626 | | Unit Count | 1 Count | ## Product Details - **Brand:** CARBO INSTRUMENTS - **Item Weight:** 5.76 ounces - **Item dimensions L x W x H:** 4.41 x 3.74 x 1.3 inches - **Material:** Brass and Copper alloy Wetted Parts - **Number of Items:** 1 ## Images ![4000 PSI Glycerin Liquid Filled Pressure Gauge, 2.5" Dial, 1/4 NPT Lower Mount, 304 Stainless Steel Case, Brass Wetted Parts, Dual Scale PSI/Bar - ASME B40.1 Grade A - Image 1](https://m.media-amazon.com/images/I/71GsNCg4acL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very Good *by S***E on March 30, 2025* Great purchase.
