Product Overview
Low Pressure Rubber Tapered Plugs
Neoprene — Temporary & Low-Pressure Applications

A cost-effective alternative to higher-cost tube plugs for temporary or low-pressure applications. Made of resilient neoprene, these plugs are commonly used for low-pressure isolation or vacuum testing — including use with our Vacuum Leak Detector (VLD-2500). One size fits multiple port sizes.

Material
Resilient neoprene construction — soft rubber conforms to the tube interior for a tight, reliable seal across multiple port sizes.
Temperature Range
Temperature resistant from -25°F to 180°F (-31°C to 82°C) — suitable for a broad range of service conditions.
Applications
Ideal for low-pressure isolation and vacuum testing — designed for use alongside the USA Industries Vacuum Leak Detector (VLD-2500).
Availability
500,000+ tube plugs in stock and ready to ship — in-stock items ship within 24 hours.
Ease of Installation
Install with a simple press fit — remove with a tap of a rubber mallet or the pull of pliers. Reusable with proper installation and care. One size fits multiple port sizes, minimizing inventory requirements.
