If you have ever run a joint test on a pipeline using PlugCo’s Joint Tester, you know already about PlugCo’s Control Device for Joint Tester. It is not just a control box, it is the brain of your test setup.
When you are working with air or water pressure, things can go wrong fast if you don’t have full control. PlugCo’s Control Device makes sure you do.
So, What Exactly Is the Control Device for Joint Tester?
In simple terms, it is a pressure monitoring and regulation unit that connects directly to PlugCo Joint Testers. It controls everything from start to finish:
- Inflating the sealing bladders
- Regulating the test pressure between the bladders
- Monitoring pressure changes
- Safely discharging air or water after the test
Instead of juggling multiple valves, gauges, or hoses, you manage the entire process from a single, compact unit, built specifically for this job.
Why It is Worth Using the Control Device of Joint Tester Every Time?
1. It Lets You Inflate the Bladders Precisely
Each PlugCo Joint Tester has two inflatable bladders and both need to be inflated accurately.
Why this matters:
- Prevents leaking
- Ensures the test chamber is properly sealed
- Reduces wear and tear on the equipment
2. You Get Accurate Test Pressure Control
Once the bladders are sealed in place, you inject air or water into the chamber between them, and this is where precision matters most.
The Control Device helps you:
- Set the exact test pressure
- Keep an eye on it with real-time monitoring
- Spot leaks immediately based on any pressure drop
This is not just helpful, it is critical. A few seconds of pressure loss can tell you exactly where a joint is compromised.
3. It Makes Testing Safer for Everyone
Releasing pressure from a joint test can get messy, and dangerous, if not done carefully.
PlugCo’s Control Device guides you through the correct discharge sequence:
- First, release the test pressure safely.
- Then, deflate the bladders in a controlled way.
- Avoid sudden blowouts, water sprays, or damaged equipment.
This also means no last-minute surprises when you are pulling equipment out of a manhole or trench.
4. It Works with Both Air and Water
Whether you are running air pressure tests or hydrostatic (water) tests, this Control Device handles both without needing any special conversion. Just hook up your compressor or water tank and go.
This flexibility makes it ideal for:
- Municipal inspections
- Utility contractors
- Trenchless rehab crews
- QA teams on new installs
A Few Features That Make the Control Device of Joint Tester Stand Out
- High-accuracy gauges
- Quick-connect ports for all hoses
- Rugged, portable design with legs and carrying handle
- Air-Water test compatiblity
- Compatibility with all PlugCo’s Models of Joint Tester
