Fits 14mm and 18mm thread sizes. Review: Very accurate - Works perfectly and is just as accurate much cheaper as my snap on. Review: Ready to go right out the box, good quality and price - The item itself came with an attachment to allow for both testing compression of 14 and 18mm threading. I was able to quickly thread it in, get the measurement of compression, and move on to the next spark plug with no fuss. It is of sturdy build, easily readable, and feels like it will last. I just wish it came with a different way to store it after opening the packaging, it was wrapped with a (albeit a decent quality) rubber band. ## Features - Quickly and Accurately Check Compression on Gasoline Engines. - Gauge registers 0 - 300 P.S.I. and 0 - 2100 kpa. - Fits 14mm and 18mm thread sizes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0009OMYH4 | | Best Sellers Rank | #37,946 in Automotive ( See Top 100 in Automotive ) #30 in Engine Compression Gauges #1,166 in Diagnostic, Test & Measurement Tools | | Brand Name | Lisle | | Customer Reviews | 4.5 4.5 out of 5 stars (146) | | Global Trade Identification Number | 00083045202509 | | Included Components | Tester | | Item Dimensions | 14.5 x 4.75 x 2.75 inches | | Item Type Name | Tools | | Manufacturer | Lisle | | Material Type | Plastic | | UPC | 083045202509 | | Unit Count | 1.0 Count | | Warranty Description | Limited Lifetime | ## Product Details - **Brand:** Lisle - **Item dimensions L x W x H:** 14.5 x 4.75 x 2.75 inches - **Material:** Plastic - **Thread Type:** Metric - **Voltage:** 1 ## Images ![20250 Compression Tester - Image 1](https://m.media-amazon.com/images/I/610orW4eiqL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very accurate *by T***H on December 11, 2025* Works perfectly and is just as accurate much cheaper as my snap on. ### ⭐⭐⭐⭐⭐ Ready to go right out the box, good quality and price *by W***E on July 31, 2025* The item itself came with an attachment to allow for both testing compression of 14 and 18mm threading. I was able to quickly thread it in, get the measurement of compression, and move on to the next spark plug with no fuss. It is of sturdy build, easily readable, and feels like it will last. I just wish it came with a different way to store it after opening the packaging, it was wrapped with a (albeit a decent quality) rubber band. ### ⭐⭐⭐⭐⭐ Accurate Product, Great Value, Worked for me. *by M***K on August 14, 2021* I recently had misfiring code displaced on my 2001 Honda Accord. I changed the spark plus and coiled, but this did not solve the issue. So I decided that I needed to check the compression on my cylinders to find out if I had a more serious engine problem. I bought this compression tester because it was American made and had a reasonable price. I tested all 4 cylinder compressions with this tool. All cylinders averaged 175 PSI or better. I tested each cylinder twice to ensure that the results were repeatable. So I now know that that compression is great on my car's engine and it is not the problem for the misfire. Though this hasn't solved my misfire problem it has eliminated a potential major problem. I would recommend this product to anyone who needs to do this test. This is a great product and a welcome addition to my tool library. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/12684212-20250-compression-tester](https://www.desertcart.kr/products/12684212-20250-compression-tester) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-18*
