Review: Great inflatable bladder, great addition to evap/smoke machine kit, spare sleeve in kit as well Review: Bladder filled my CAI S&B on my Cummins. Sealed well and held long enough for me to find my boost leaks until the bladder slipped out from the intake tube. Its smooth plastic so it was bound to slip after high pressure. Works great and came with spare bladder. ## Features - 【 BLADDER MODE 】 For injecting smoke into large openings. Insert the deflated bladder and inflate with the built-in hand pump. - 【 PLUG MODE 】 For blocking off smoke. Tuck the input hose into the rear of the bladder to crimp it and block off the bladder turning it into an inflatable plug. - 【 WIND/WATER LEAK MODE 】 For testing door jambs for leaks. How: MAX A/C blower fan. Turn OFF circulation. Close all doors and build positive air pressure inside cabin. Air will naturally escape through leaks in door jambs. Run smoke through Universal Bladder for a slow steady stream of thick smoke. Guide it through your door jambs until you see turbulent air blowing the rising smoke. - 【Backup Bladder】 Extra Bladder Included! - 【CarbonNitrile】 Industrial & Automotive Grade ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BVZN5N4G | | Assembly Required | No | | Brand | AutoLine Pro | | Country of Origin | USA | | Customer Reviews | 4.2 4.2 out of 5 stars (245) | | Date First Available | 27 October 2023 | | Generic Name | Bladder Adapter for Automotive Smoke Leak Testing | | Item Weight | 181 g | | Item model number | Universal Bladder Adapter | | Manufacturer | AutoLine Pro | | Manufacturer Part Number | Universal Bladder Adapter | | Material | CARBON NITRILE ™ | | Model | Universal Bladder Adapter | | Package Dimensions | 17.5 x 11.71 x 4.8 cm; 181 g | | Size | Adapter | | Special Features | 3-in-1 Function, CARBON NITRILE ™ | ## Images ![AutoLine Pro Best Ranked Bladder Adapter 2.0 | Automotive Smoke Testing 1.5 to 6" (38-152mm) Diameter Openings | 3-in-1 Functions as Bladder, Inflatable Plug, and Smoke Diffuser for Water Leak Testing - Image 1](https://m.media-amazon.com/images/I/31HnE5Ya9zL.jpg) ![AutoLine Pro Best Ranked Bladder Adapter 2.0 | Automotive Smoke Testing 1.5 to 6" (38-152mm) Diameter Openings | 3-in-1 Functions as Bladder, Inflatable Plug, and Smoke Diffuser for Water Leak Testing - Image 2](https://m.media-amazon.com/images/I/41+DQc+xslL.jpg) ![AutoLine Pro Best Ranked Bladder Adapter 2.0 | Automotive Smoke Testing 1.5 to 6" (38-152mm) Diameter Openings | 3-in-1 Functions as Bladder, Inflatable Plug, and Smoke Diffuser for Water Leak Testing - Image 3](https://m.media-amazon.com/images/I/41Wj2fpycdL.jpg) ![AutoLine Pro Best Ranked Bladder Adapter 2.0 | Automotive Smoke Testing 1.5 to 6" (38-152mm) Diameter Openings | 3-in-1 Functions as Bladder, Inflatable Plug, and Smoke Diffuser for Water Leak Testing - Image 4](https://m.media-amazon.com/images/I/41bdry7iPOL.jpg) ![AutoLine Pro Best Ranked Bladder Adapter 2.0 | Automotive Smoke Testing 1.5 to 6" (38-152mm) Diameter Openings | 3-in-1 Functions as Bladder, Inflatable Plug, and Smoke Diffuser for Water Leak Testing - Image 5](https://m.media-amazon.com/images/I/41fjFrNNniL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***E on 15 January 2026* Great inflatable bladder, great addition to evap/smoke machine kit, spare sleeve in kit as well ### ⭐⭐⭐⭐⭐ Review *by C***N on 30 October 2025* Bladder filled my CAI S&B on my Cummins. Sealed well and held long enough for me to find my boost leaks until the bladder slipped out from the intake tube. Its smooth plastic so it was bound to slip after high pressure. Works great and came with spare bladder. ### ⭐⭐⭐⭐⭐ Review *by S***N on 11 March 2025* Far superior to all the other knock off brands, the expansion will actually plug a 6" pipe, the others couldn't plug a 4" without being able to see through the bladder and having it pop under any heat or pressure. The injection baffle is a very nice touch as well --- ## 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.hr/products/622073665-autoline-pro-best-ranked-bladder-adapter-2-0-automotive-smoke](https://www.desertcart.hr/products/622073665-autoline-pro-best-ranked-bladder-adapter-2-0-automotive-smoke) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-15*
