Pure Rubber Inflatable Pipe Plug
Pure rubber pipe plug – no fabric reinforcement, lightweight and economical. Φ50-600mm, 0.015MPa. Ideal for small pipe sealing, testing, and maintenance. Low cost, easy use.
Pure Rubber Inflatable Pipe Plug – Economy, Lightweight, for Small Diameter Pipes (Φ50-600mm)
Our pure rubber inflatable pipe plug (also known as economy pipe plug or lightweight sealing plug) is a simple, cost-effective solution for temporarily sealing small diameter pipes. Made of 100% pure rubber without any internal fabric reinforcement, it is flexible, easy to operate, and ideal for low-pressure applications where economy and convenience are priorities. Suitable for pipe diameters from Φ50mm to Φ600mm, with an inflation pressure of 0.015 MPa, it is perfect for residential plumbing testing, small sewer lines, drainage systems, and light maintenance work.
What is a Pure Rubber Inflatable Pipe Plug?
A pure rubber inflatable pipe plug is a solid rubber bladder that expands when inflated to seal the pipe. Unlike heavy-duty reinforced plugs, this product has no fabric layers, making it thinner, lighter, and much more affordable. It is designed for low-pressure sealing (≤0.015 MPa) and small pipe diameters. While it has a lower pressure rating than multi-layer plugs, it offers excellent flexibility and ease of use for non-critical applications.
Key Features
- Pure rubber construction – No fabric reinforcement, lightweight and flexible.
- Low inflation pressure – 0.015 MPa (2.2 PSI) – safe for plastic, clay, and concrete pipes.
- Wide size range – Covers small diameters from Φ50mm up to Φ600mm.
- Economical – Much lower cost than reinforced pipe plugs.
- Easy to use – Insert deflated, inflate with a hand pump, deflate and remove.
- Reusable – Can be used many times for testing and temporary sealing.
- Corrosion resistant – Rubber withstands water and mild sewage.

Applications
Our pure rubber inflatable pipe plugs are ideal for:
- Residential plumbing testing – Sealing drains and waste pipes for water tests.
- Small sewer lines – Temporary blocking during cleaning or CCTV inspection.
- Drainage systems – Isolating sections for repair or maintenance.
- Pipe leak testing – Low-pressure air or water testing of new installations.
- DIY projects – Simple sealing for home construction or repair.
- Temporary pipe shut-off – When a quick, cheap seal is needed.
How to Use (Installation Guide)
- Select the correct size – Choose the model that matches your pipe’s internal diameter.
- Insert deflated plug – Push the plug into the pipe to the desired position.
- Connect hand pump – Attach a manual hand pump or low-pressure compressor to the valve.
- Inflate slowly – Inflate to 0.015 MPa. Do not exceed this pressure as the plug has no fabric reinforcement.
- Check the seal – Ensure the plug is snug and no water/air leaks.
- Deflate and remove – After work is complete, release air and pull the plug out.
- Clean and store – Rinse with water, dry, and store away from sharp objects and sunlight.
Frequently Asked Questions (FAQ)
Q: Why is this plug cheaper than others?
A: This plug is made of pure rubber without any fabric reinforcement. It is designed for low-pressure, small-diameter applications. For higher pressure or larger pipes, we recommend our reinforced multi-layer plugs.
Q: Can it be used in PVC pipes?
A: Yes. The low inflation pressure (0.015 MPa) is safe for PVC, ABS, clay, and concrete pipes without risk of deformation.
Q: How many times can it be reused?
A: With proper care (avoiding cuts and over-inflation), it can be reused dozens of times. Inspect for cracks or thinning before each use.
Q: What is the maximum back pressure it can hold?
A: Approximately 0.015 MPa, which corresponds to about 1.5 meters of water head. Not suitable for high-pressure testing.
Q: Do you have other sizes below Φ50mm or above Φ600mm?
A: Yes, smaller sizes (down to Φ25mm) are available on request. For larger than Φ600mm, please see our reinforced pipe plug series.
