Onnline test plug 1/2" PVC red for leak testing (F-693341-P)

The Onnline test plug 1/2" PVC red is a temporary sealing device designed to close pipe ends and openings during pressure and leak testing. Made from durable PVC and sized for 1/2" connections, this plug provides a simple method to isolate sections of plumbing, heating, or ventilation systems to verify tightness and locate leaks. The compact construction and bright red color make it easy to handle and identify on-site.

Advantages

This test plug offers reliable sealing performance for short-term use in leak testing and maintenance operations. Its PVC construction resists corrosion and most common fluids encountered in plumbing and HVAC environments. The 1/2" size provides compatibility with standard fittings and makes the plug convenient for quick installations and removals during diagnostic procedures.

Suitable for

• Temporary sealing of 1/2" pipe ends during pressure or leak tests
• Plumbing maintenance and repair tasks
• HVAC system tightness checks and ductwork isolation
• Workshop or site testing where a simple, visible plug is required

Key specifications

• Material: PVC (polyvinyl chloride)
• Connection size: 1/2"
• Color: red
• Intended use: temporary sealing for pressure and leak testing
• Typical applications: plumbing, heating, ventilation systems

How to use

Insert the plug into the open end of the clean 1/2" pipe or fitting, ensuring a snug fit. Apply the test pressure gradually while observing the sealed section for signs of leakage. If necessary, adjust the plug position to improve the seal. After testing, release the pressure following safety procedures and remove the plug by pulling it out from the pipe end. Clean and inspect the plug before storing it for future use.

Usage recommendations

Before use, confirm compatibility between the plug material and the fluids or gases in the system. Do not exceed the pressure limits appropriate for PVC components and follow local safety standards for pressure testing. Use the plug only for temporary testing purposes and avoid prolonged exposure to solvents or extreme temperatures that may degrade PVC.
