Its innovative Direct Drive technology reduces moving parts to one, enhancing durability and eliminating the need for liquid filling through silicone coil dampening. Designed for extreme vibration and pulsation environments, this shock-resistant, UV-stabilized gauge offers overpressure protection to 150% full scale and comes with a 6-year warranty, making it the ultimate choice for professionals demanding reliability and longevity. ## Description 3D Instruments 25 series Accu-Drive test gauges incorporate the "Direct Drive Difference" Inconel helical bourdon tube system. The "Direct Drive Technology" concept couples the bourdon tube directly to the shaft-pointer, thereby streamlining the design and reducing the number of moving parts from approximately twelve down to one. Thirty years of industrial application have proven that this design is vastly superior to the C-bourdon tube/movement system incorporated in the traditional pressure gauges specially for vibration and pulsation. The Series 25 "Direct Drive Difference" approach applies silicone dampener directly to the bourdon tube. This "coil dampening" approach isolates the pointer from vibration and pulsation, thereby eliminating the requirement for liquid filling of the gauge case. In most instances, a standard 3D Accu-Drive pressure gauge can directly replace an "old fashioned" liquid filled gauge without creating the maintenance headaches cited above. When compared to a liquid filled gauge, the Accu-Drive gauges have been shown to last as much as ten times longer in applications with extreme pulsation and vibration. The net effect of these benefits, coupled with a 6 year product warranty. Additionally, because of a lack of gears and wear points, the Accu-Drive series of gauges maintain their rated accuracy over the entire life of the gauge without the need for costly periodic recalibration. The Series 25 Accu-Drive pressure gauges utilize the finest materials of construction. The bourdon tube is constructed of Inconel, a highly elastic material with excellent corrosion resistance. All other "wetted parts" are 316 Stainless Steel. The balance of the gauge hardware is designed to minimize corrosion associated with challenging field environments. The extremely robust bourdon tube system offers outstanding overpressure protection to 150% of full scale. -65 to +190 degrees F temperature range. ## Features - Helically wound inconel bourdon tube - Precision anti-friction sapphire shaft bearings - Shock resistant and UV stabilized - Adjustable zero set-point - 6 Year warranty ## Product Details - **Brand:** 3D Instruments - **Material:** ABS Plastic - **Manufacturer:** 3D Instruments ## Images ![25 Series Accu-Drive ABS Plastic Case Pressure Test Gauge with Stainless Steel 316 Internals and Panel/Wall Mount, 4-1/2" Dial, 0-3000 psi Range, +/- 1% Accuracy, 1/4" Male NPT Bottom Connection, Black - Image 1](https://m.media-amazon.com/images/I/91VUCpzjEYL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/36921647-25-series-accu-drive-abs-plastic-case-pressure-test-gauge](https://www.desertcart.co.za/products/36921647-25-series-accu-drive-abs-plastic-case-pressure-test-gauge) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-07*
