Products Description
| Product Type | Air conditioner counterweight block with C-clip assembly |
| Product Form | Complete assembly consisting of rubber counterweight block + C-shaped open spring clip |
| Primary Application | Securing the counterweight block on refrigerant piping to prevent displacement or loosening under vibration |
| Functional Features | Elastic clamping, vibration resistance, anti-loosening; suppresses pipe resonance and reduces operational noise |
| Material | Counterweight block: rubber composite; C-clip: 65Mn spring steel with phosphating anti-corrosion treatment |
| Application Scenarios | Refrigerant piping in split-type air conditioners and central air conditioning systems |
| Installation Method | Pre-assembled components; snap-on installation on-site for quick assembly |
| Core Advantages | Precisely matched counterweight and C-clip assembly ensures dimensional accuracy and meets piping vibration-damping requirements |
| Certifications | ISO9001, RoHS, REACH, IATF16949 |
Product Advantages

Product Advantages
- Integrated assembly supply – the damping counterweight and C-clip are pre-sized, saving customers from separate purchasing and pairing/testing procedures.
- The clip features phosphating surface treatment for rust prevention and withstands high/low temperature cycling, suitable for harsh outdoor AC unit temperature conditions.
- Quick snap-on installation simplifies assembly and improves production line efficiency for customers.
- Customization of counterweight specifications and clip thickness is available, with stable capacity for high-volume orders.
- The positive locking mechanism prevents the counterweight from shifting during long-term operation, enhancing system reliability.
Installation Instructions
Snap the rubber damping counterweight onto the refrigerant piping.
Insert the C-clip into the pre-formed groove on the counterweight.
Press the clip firmly until it fully engages and locks; verify that the counterweight shows no movement.

Application Scenarios & Precautions

Application Scenarios
Vibration and noise reduction for refrigerant piping in split-type air conditioners and central AC indoor/outdoor units; effectively suppresses piping vibration and reduces overall unit resonance noise.
Precautions
- Ensure the C-clip is fully seated into the counterweight groove – do not install it in a half-engaged position.
- Do not over-expand the clip beyond its elastic limit, as permanent deformation will result in loss of clamping force.
- Store in a dry, well-ventilated area; prolonged storage in damp conditions may cause rust on the clip.
- Strictly verify the pipe outer diameter and counterweight specifications – do not mix components of different sizes.
- After installation, perform sample vibration tests to confirm that the counterweight does not slip.

Performance Comparison
| Aspect | Air conditioner counterweight block with C-clip | Traditional clamp-type or adhesive-attached counterweights |
|---|---|---|
| Installation Efficiency | Snap-on assembly, no extra tools or testing required | Often requires screws, straps, or adhesive curing time – slower |
| Fit Precision | Pre-matched to size, zero clearance deviation | Prone to mismatched sizes, requiring on-site adjustment |
| Anti-Loosening Reliability | Positive C-clip locking, prevents slippage under vibration | May loosen over time due to thermal cycling and continuous vibration |
| Corrosion Resistance | Phosphated spring steel, suitable for outdoor exposure | Many traditional clips lack anti-corrosion treatment |
| Maintenance | Easy to inspect visually; clip engagement is clear | Difficult to verify tightness without disassembly |
