By pressurizing a cylinder and measuring how much leaks, you can gain actionable clues about engine sealing and performance, guided by realistic testing workflows.\u003c\/p\u003e\n\u003ch2\u003eOverview\u003c\/h2\u003e\n\u003cp\u003eThe kit combines a dual gauge setup that records both the air pressure in the tested cylinder and the leak rate simultaneously. The pressure gauge covers 0-100 psi and 0-7 bar, while the leak gauge reads 0-100 percent, with a typical accuracy around 0.5 percent. This arrangement supports quick, side-by-side comparisons and helps you interpret results in the context of a spark-plug equipped gasoline engine within a 20 mm plug-well specification.\u003c\/p\u003e\n\u003ch3\u003eWhat’s included\u003c\/h3\u003e\n\u003cp\u003eIn addition to the common core, the package expands to offer flexible, field-ready testing options. The kit includes a double gauge manifold, an 18 inch hose, an AR2000 pressure-regulating valve, an American type air plug, and a sturdy manifold body. It also provides two universal push-on connectors and two threaded adapters, plus a 14 mm extension rod and an extension hose for longer reach.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble gauge manifold and 18 inch hose for integrated readings\u003c\/li\u003e\n  \u003cli\u003eAR2000 pressure regulating valve with a lockable knob\u003c\/li\u003e\n  \u003cli\u003eTwo universal push-on connectors and two threaded adapters\u003c\/li\u003e\n  \u003cli\u003eM14 aluminum extension rod with extension hose\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow it works in practice\u003c\/h3\u003e\n\u003cp\u003eHook the kit up to an air compressor (your setup), attach the push-on connectors to the spark plug wells, and pressurize to observe the readings. The dual gauges provide a live view of the cylinder pressure and the leakage percentage, while the valve knob lets you manage input air.

While the tool supports directional testing and trend comparison, outcomes depend on correct setup, engine type, and proper calibration with your compressor.\u003c\/p\u003e\n\u003cp\u003eOverall, the Prokomon tester kit aims to offer a practical, non-invasive way to gain insights into cylinder sealing and leak behavior. It can fit into routine diagnostic routines or as a focused check during maintenance sessions, helping you decide what further investigation may be warranted.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What is included in the Prokomon Cylinder Leak-Down Tester Kit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The kit includes a double gauge manifold, hoses, metal adapters, push-on connectors, threaded adapters, an M14 extension rod, and an extension hose.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How can this tester help in diagnosing engine issues?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It records cylinder pressure and leak rate to help reveal potential faults like ring wear, valve wear, or gasket leaks; results depend on proper setup and engine compatibility.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Prokomon","offers":[{"title":"Default Title","offer_id":42469704106069,"sku":"B0G48PSZKW","price":56.07,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/3270\/4597\/files\/prokomon-engine-cylinder-leak-down-tester-kit-front-view.jpg?v=1778104005","url":"https:\/\/plentytorque.co.uk\/products\/prokomon-engine-cylinder-leak-down-tester-kit-dual-gauge-extension-rod-grey-4-piece-set","provider":"PlentyTorque","version":"1.0","type":"link"}
