How to use our Plastic Hole Plugs?
Plastic hole plugs from the KHP series are designed for simple press-fit installation into drilled or punched panel openings. They conceal screw heads, nuts and raw holes while providing a sealing barrier against dust and liquid ingress. Intended for use on metal, plastic and composite panels where a clean finish and basic sealing are required.

Advantages

• Corrosion resistance: Polymer construction prevents corrosion issues at the closure point.
• Mechanical resistance: Retention and impact resistance suitable for assembly and handling; typical service temperature range −20°C to +85°C (material- and grade-dependent).
• Chemical resistance: Suitable against a broad range of chemicals depending on material selection.
• Aesthetic finish: Flush appearance to improve the visual finish of assemblies.
• Range and customization: Available in PA66 grades for increased strength, with multiple colours, shapes and sizes for standard and custom requirements.

Applications

• Automotive: Bumpers, interior trim, seat components and other vehicle panels.
• Appliances: Covering fixings and openings on household equipment.
• HVAC: Sealing openings in ventilation, heating and air-conditioning panels.
• Metal construction & assembly: Protective closure for panels and machinery assemblies.
