WVA-132 | Small Bladder Plug with Through-Hole

The MotorVac WVA-132 Small Bladder Plug is an essential accessory for smoke machine leak testing, designed to seal small diameter openings from 1.25″ up to 4″ in various automotive systems. This versatile plug is particularly useful for EVAP system testing, exhaust leak detection, intake manifold testing, and other applications requiring secure sealing of pipes, hoses, or openings.

The through-hole design allows smoke or test gas to pass through the bladder while maintaining a secure seal around the opening, making it ideal for introducing smoke into closed systems during leak detection procedures. The included hand pump enables quick and easy inflation to achieve the desired seal, with visual confirmation of proper expansion.

The flexible body construction allows the bladder to conform to curved applications, making it effective in situations where rigid plugs would fail. The patented bladder design conforms to both round and irregular shapes, ensuring reliable sealing even in non-standard pipe configurations or damaged openings. This flexibility makes the WVA-132 particularly valuable for testing exhaust systems with curved tailpipes, EVAP system lines with bends, or any application where the test point isn’t perfectly straight or cylindrical.

Compatible with all MotorVac smoke machines including the Vacutec Leakfinder and CoolSmoke systems, the WVA-132 expands the diagnostic capabilities of your leak detection equipment by providing secure sealing for a wide range of pipe and opening sizes.

• Expandable range: 1.25″ expands to seal openings up to 4″ diameter
• Through-hole design: Allows smoke passage while maintaining seal
• Flexible body: Conforms to curved applications and irregular shapes
• Hand pump included: Easy inflation for quick sealing
