## Overview

The AutoLine Pro Universal Bladder Adapter is a professional-grade, 3-in-1 inflatable tool designed for automotive smoke testing. It fits openings from 1.5" to 5" (38-130mm) and functions as a bladder, plug, and smoke diffuser to detect leaks efficiently. Made from durable CarbonNitrile material and backed by a 3-year warranty, it includes a spare bladder for uninterrupted testing.

## Description

For large openings, exhausts, intake, and more!

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
- THREE-YEAR WARRANTY: You're fully covered from all manufacturer and operational defects. We're right here in the United States and will replace your unit or parts - fast and hassle free :)

*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
