Housed in a corrosion-resistant steel case with a break-resistant lens, it delivers reliable pressure monitoring and protection for industrial engines and equipment, meeting SAE standards and designed for demanding environments. ## Description The 20P7-100 Pressure Swichgage with lockout, is a 2" dial, diaphragm-actuated pressure-indicating gage with a built-in electrical limit switch, which is used for tripping alarms and/or shutdown devices. This dual-scale instrument has a range of 0-100 psi (690 kPa) [7.0 bar]. The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged instrument. Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. On the 20P7-100, the low limit contact can be by-passed on start-up by pushing the lockout button. It holds the pointer away from the shutdown contact while the engine starts. The lockout will disengage automatically on rising pressure. Additionally, the gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts are grounded through the case and have a self-cleaning motion to ensure electrical continuity. The 20P7-100 Pressure Swichgage was specifically designed to protect engines and equipment in oil field, marine, irrigation, construction and trucking applications by monitoring engine lube pressure, water pump pressure, hydraulic pressure and air pressure. This popular instrument features a beryllium copper diaphragm, a 1/8-27 NPTM brass process connection, and exceeds SAE standards. ## Features - The 20P7-100 Pressure Swichgage is a 2" dial, diaphragm-actuated pressure-indicating gage with a built-in electrical limit switch. This dual-scale instrument features a lockout button and has a range of 0-100 psi. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZHQ3ZVV | | Best Sellers Rank | #219,521 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #454 in Industrial Pressure Gauges | | Date First Available | October 23, 2019 | | Item Weight | 7.8 ounces | | Manufacturer | Murphy by Enovation Controls | | Package Dimensions | 3.07 x 2.83 x 2.72 inches | ## Product Details - **Brand:** Murphy by Enovation Controls - **Manufacturer:** Murphy by Enovation Controls - **Material:** Brass, Polycarbonate (PC), Stainless Steel - **Thread Type:** 1/8-27 Npt ## Images ![20P7-100, 2" Pressure Swichgage w/Lockout, 0-100 psi (05703207) - Image 1](https://m.media-amazon.com/images/I/71bUYlw8sEL.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.vu/products/206818825-20p7-100-2-pressure-swichgage-w-lockout-0-100-psi](https://www.desertcart.vu/products/206818825-20p7-100-2-pressure-swichgage-w-lockout-0-100-psi) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-16*
