KNOKOO Black Round Pipe Plugs | For Sealing Welding Fume Purifier Piping Systems | Dustproof and Leak proof Accessories

When your KNOKOO smoke purifier duct system needs layout adjustments and there are excess duct interfaces lying around, open ports can lead to serious air leaks, reduced purification efficiency, and even become entry points for dust backflow. This KNOKOO original black round duct plug is designed to solve this small but crucial problem. Specifically designed for standard 83mm inner diameter ducts, it provides a tight physical seal, ensuring your suction system maintains complete negative pressure, making every drop of suction power effectively utilized. It's an essential accessory for efficient duct system management and daily maintenance.

1. Precise Size, Seamless Fit

Features: Strictly matches KNOKOO standard ducts, 83mm inner diameter, 100mm outer diameter, with a highly adaptable round design.

Benefits: A tight fit after insertion effectively prevents air leakage from unused ports, avoiding unnecessary loss of system suction power and ensuring efficient smoke capture at the source.

2. Durable Material, Professional Fit

Features: Made of durable black material, visually consistent with original ducts, and resistant to dirt.

Benefits: Ensures long-term reliability; optimized specifically for KNOKOO systems, avoiding installation instability or poor sealing issues caused by incompatible parts.

3. Clear Function, One-Click Sealing

Features: Single and clear function—used for permanent or temporary sealing of unused pipe interfaces.

Benefits: Quickly seals pipes when adjusting workstation layout or temporarily shutting down an air intake or storage device, maintaining the cleanliness of the entire purification system and preventing dust and debris from entering.

4. Plug and Play, Easy Maintenance

Features: No tools required; simple manual installation and disassembly.

Benefits: Easy for ordinary users to operate, greatly simplifying daily management and maintenance of the piping system.

Product use

1. Maintenance and Cleaning

• Regular cleaning of the plug helps prevent debris buildup, ensuring an unobstructed airflow.

• Inspect the surface of the plug for any signs of blockage or contamination and wipe it clean as needed.

• Avoid the use of abrasive cleaning agents that may damage the surface or reduce its sealing capacity.

2. Replacement Instructions

• The pipe plug should be replaced immediately if any damage or wear is observed. Signs such as cracks, deformation, or visible degradation compromise its effectiveness and can reduce the overall performance of the fume extractor system. Regular checks ensure any potential issues are addressed promptly, maintaining the safety and efficiency of the system.

3. Precautions

• Replacement Timing: Replace the pipe plug as soon as damage is detected. Delayed replacement can impact the system’s ability to effectively remove pollutants.

• Proper Installation: Make sure the plug is securely installed in the pipe to prevent air leakage or system inefficiency.

• Use Original Accessories: Always choose genuine KNOKOO parts to ensure compatibility and maintain the high efficiency of the fume extractor. Non-original components may lead to reduced performance or system failure.

• Regular Inspections: Conduct routine checks to identify any signs of damage or wear. Timely detection and replacement are key to ensuring consistent air purification performance.
