Product Advantages
Product Advantages
1. Comprehensive Size Coverage
121 size variants covering hole diameters from 2.5mm to 200mm, including standard and short-length versions. Most models are available from stock for fast delivery.
2. T-Flange Anti-Loss Design
The top flange structure ensures the plug cannot fall completely into the copper pipe or cavity, preventing foreign object contamination-critical for heat pump brazing processes .
3. Silicone Elastic Sealing
Soft silicone provides elastic compression to conform to hole walls, delivering dustproofing, contamination prevention, and basic moisture resistance to protect piping cleanliness .
4. Tool-Free Installation
Manual press-in insertion and direct pull-out removal-adapts to multi-station production workflows without damaging copper pipe ends .
5. Versatile Applications
Suitable for heat pump copper pipe protection, sheet metal opening sealing, equipment anti-impact pads, hole covering, and more.
Installation Instructions
Size Verification: Confirm the copper pipe or hole inner diameter and select the corresponding T-Shaped Silicone Plug model .
Press-Fit Installation: Align with the pipe opening and press the plug body into the hole until the flange sits flush against the pipe end face.
Removal: When brazing or assembly is required, grip the flange top and pull the plug out directly.
Application Scenarios & Precautions
Application Scenarios
- HVAC & Heat Pump Industry: Copper pipe protection during production, sealing both ends before brazing to prevent dust, metal chips, and contaminants from entering the piping; temporary sealing during multi-station transfer .
- Sheet Metal & Enclosures: Covering and dustproofing for pre-drilled holes in sheet metal and equipment panels .
- Furniture & Hardware: Equipment feet pads, hole covering for aesthetic purposes .
- General Pipe Processing: Temporary dustproof protection for various pipe ends during processing.
Precautions
- This product is designed for temporary process protection only, not for pressure sealing. It cannot withstand high-pressure gas or liquid-for dust and contamination prevention only .
- Size selection: Verify the actual hole inner diameter before ordering. Incorrect sizing may result in the plug falling out or being impossible to install .
- For heat pump brazing: All plugs must be completely removed before brazing. Silicone carbonizes at high temperatures, leaving residues that contaminate copper pipes .
- Standard vs. Short versions: Standard length is recommended for best sealing. Use the short version only where space is limited-it has reduced sealing performance .
- Testing: Request samples for actual installation testing to verify fit and sealing effectiveness before bulk ordering.
Performance Comparison

Comparison |
T-Shaped Silicone Plug |
Snap-Fit Plug |
|
Fastening Principle |
Elastic interference fit-silicone deforms to conform to hole wall |
Snap-lock barbs grip the hole wall for fixation |
|
Installation/Removal |
Easy-press in by hand, pull out directly |
Simple installation, difficult removal; barbs may break leaving debris |
|
Pipe Contamination Risk |
T-flange prevents loss; minimal debris risk |
Broken barbs can leave fragments inside copper pipes |
|
Size Range |
2.5–200mm, extensive range |
3-60mm, Mostly small to medium holes; limited large-size options |
|
Best Use Case |
Temporary protection during production, frequent removal/installation |
Long-term fixed sealing; not recommended for piping requiring subsequent welding |
