Product Description

Wall Cover-QG

Definition: The QG Series is an injection-molded PVC wall cover designed for mini split line set cover systems. It conceals the wall opening where insulated refrigerant pipes, condensate drain hoses and control cables pass through the wall, while providing a clean transition to a compatible GG straight duct. Three sizes are available for different wall openings and pipe bundles. The QG Wall Cover is intended for decorative covering and basic protection and should not be used as a pipe-support or load-bearing component.

Specification

Application Scenarios:

•Covering air-conditioning pipe entry points 

•Connecting indoor and outdoor pipe-cover routes 

•Connection with compatible GG straight ducts 

•Residential, apartment, office and retail HVAC installations 

•Renovation of existing wall openings and exposed pipework 

Core Materials and Manufacturing

The QG Wall Cover is normally manufactured from injection-molded PVC. It is lightweight, easy to clean and does not develop metal rust.

The main production processes include:

• PVC raw-material preparation and color matching 

• Injection molding and cooling 

• Edge trimming and surface finishing 

• Dimensional and interface inspection 

• Appearance and color-difference inspection 

• Compatibility testing 

• Packaging and batch identification 

 Injection molding helps maintain consistent external profiles, fixing positions and connection dimensions.

 White is the standard color. Customized colors, logos, labels and packaging are available according to order requirements.

Manufacturing Advantages:

• Clean wall finish: Conceals pipe-entry openings and installation marks. 

• Continuous transition: Connects the wall penetration to the straight duct. 

• Basic protection: Helps reduce the entry of dust and installation debris. 

• Three size options: Suitable for different pipe bundles and project requirements. 

• Convenient installation: One-piece molded structure with no complicated assembly. 

• Consistent appearance: Matches compatible PVC ducts in color and profile. 

• Lightweight and rust-free: PVC does not develop metal red rust. 

• Customization available: Colors, logos, labels and packaging can be customized.

FAQ

Q1: What is the QG Wall Cover used for?

The QG Wall Cover conceals the wall opening where mini split refrigerant pipes, drain hoses and control cables pass through the wall. It also connects the wall penetration to a compatible straight cover duct.

Q2: How do I select the correct QG size?

Measure the wall opening, total pipe-bundle dimensions and matching straight-duct profile. Select a model with sufficient internal clearance and wall-opening coverage.

Q3: Which GG straight duct is compatible with each QG model?

Compatibility depends on the actual connection profile. The matching relationship between QG-1/QG-2/QG-3 and GG straight ducts should be confirmed in the product compatibility chart before ordering.

Q4:  Is the QG Wall Cover waterproof?

The QG Wall Cover is primarily a decorative and protective cover. Where waterproofing is required, the wall penetration should be sealed separately with a suitable sealing material.

Q5: Are screws and straight ducts included?

The listed price should clearly state whether mounting screws are included. GG straight ducts and other fittings are sold separately unless otherwise specified.
