Closed Rubber Grommets

Closed rubber grommets, also known as blind grommets or blank grommets, are essential sealing components designed to block off unused cable entry points in panels and enclosures. These push-fit rubber seals provide an airtight barrier against dust, moisture, and debris ingress whilst maintaining compliance with electrical and safety standards. Manufactured from high-grade TPE and PVC rubber materials, closed grommets offer exceptional durability and flexibility for secure panel hole sealing applications.

Widely used across the UK electronics, telecommunications, automotive, manufacturing, and construction industries, these blind rubber grommets are particularly effective for sealing unused holes in control panels, switch boxes, electrical enclosures, and machinery housings. Their simple push-fit installation requires no adhesives or fixings, with the rubber properties ensuring they remain securely in place. The closed mid-section design prevents contamination and accidental contact whilst ensuring system integrity and regulatory compliance.

Available Materials and Style Options:

• TPE (Thermoplastic Elastomer) - High flexibility and durability
• PVC (Polyvinyl Chloride) - Chemical and weather resistance
• Standard black finish for professional appearance
• Round closed design with solid centre section
• Push-fit installation style
• Panel thickness compatibility from 0.8mm to 4mm
• Mounting hole diameters from 6.4mm to 42mm

Key Features and Benefits:

• Airtight seal prevents dust, moisture, and debris ingress
