It forms a durable, pressure-resistant solid without clogging or foaming, is safe for plastic and rubber parts, and works instantly with no odors or priming required. ## Description Product Description Oatey 30115 Hercules Boiler Liquid Stop Leak, 1-Quart From the Manufacturer Seals and repairs cracks or leaks in steam or hot water heating boilers. Prevents steam boiler surging and will not clog or coat submerged hot water heating coils, controls, vents or valves. Makes a strong, lasting repair on difficult leaks in steam boilers. Tough seal expands and contracts with heat, resists pressure, and is not affected by boiler cleaners. Will not cause priming or foaming. Boiler liquid combines instantly with water in the boiler. As the water leaks through the crack, it is vaporized and the oxygen in the air transforms the boiler liquid into a strong, solid substance. The heat generated by the boiler further hardens the seal. Contains no petroleum distillates and is safe to use in boilers and systems with plastic or rubber components. Boiler liquid can be used on new installations to repair leaky joints, sand holes, etc., which may appear after an installation is completed. Ideal for older installations where corrosion causes leaks and cracks that need to be sealed. ## Features - The product is easy to use - The product is highly durable and handle - The product is manufactured in China - Seals and repairs cracks and leaks in steam and hot water systems - No odors, no priming, no foaming - As the water leaks through the crack, it is vaporized and the oxygen in the air transforms the boiler liquid into a strong, solid substance - Contains no petroleum distillates and is safe to use in boilers and systems with plastic or rubber components - Tough seal expands and contracts with heat, resists pressure and is not affected by boiler cleaners ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BQNYME | | Best Sellers Rank | #138,879 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #402 in Wall Surface Repair Products | | Brand | Oatey | | Brand Name | Oatey | | Color | color | | Compatible Material | Plastic, Rubber | | Customer Reviews | 4.6 out of 5 stars 284 Reviews | | Global Trade Identification Number | 00032628301153 | | Included Components | 1 | | Item Dimensions | 4 x 2 x 9 inches | | Item Form | Liquid | | Item Type Name | Oatey | | Item Weight | 16 ounces | | Item dimensions L x W x H | 4 x 2 x 9 inches | | Manufacturer | Oatey | | Material | solid | | Material Type | solid | | Model | 30115 | | Number of Items | 1 | | Part Number | 30115 | | Style | Compact | | Style Name | Compact | | UPC | 787461491744 032628301153 | | Unit Count | 1 Count | ## Product Details - **Brand:** Oatey - **Item Weight:** 16 ounces - **Item dimensions L x W x H:** 4 x 2 x 9 inches - **Material:** solid - **Style:** Compact ## Images ![Oatey 30115 Hercules Boiler Liquid Stop Leak, 1-Quart - Image 1](https://m.media-amazon.com/images/I/51+ODDqR3bL.jpg) ![Oatey 30115 Hercules Boiler Liquid Stop Leak, 1-Quart - Image 2](https://m.media-amazon.com/images/I/61OUI8DgWFL.jpg) ![Oatey 30115 Hercules Boiler Liquid Stop Leak, 1-Quart - Image 3](https://m.media-amazon.com/images/I/51bbfeOJCuL.jpg) ![Oatey 30115 Hercules Boiler Liquid Stop Leak, 1-Quart - Image 4](https://m.media-amazon.com/images/I/51e+5w0wu9L.jpg) ![Oatey 30115 Hercules Boiler Liquid Stop Leak, 1-Quart - Image 5](https://m.media-amazon.com/images/I/513tJE5ANoL.jpg) ## Available Options This product comes in different **Size** options. --- ## 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.ph/products/11308367-oatey-30115-hercules-boiler-liquid-stop-leak-1-quart](https://www.desertcart.ph/products/11308367-oatey-30115-hercules-boiler-liquid-stop-leak-1-quart) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-11-03*
