Protective Cap UN model SL S00085 — circular cover D100

Protective Cap UN model SL S00085 — circular cover D100 is a purpose-made circular cap with a nominal diameter of 100 mm, intended to seal openings, pipes and housings. The cap provides a physical barrier against dust, dirt and light splashes, helping to prevent contamination of internal components and simplifying maintenance operations. Its simple geometry and uniform sealing surface make it suitable for both temporary and longer-term protection in industrial, utility and maintenance environments.

Advantages

This D100 circular cover offers consistent aperture protection with an easy fit onto round openings of matching diameter. The cap’s design enables fast application and removal without special tools, reducing downtime during inspections or repairs. As a lightweight protective element, it reduces ingress of particles and droplets while maintaining access when required. The product’s standardized diameter supports interchangeability across equipment that accepts 100 mm covers.

Suitable for

• Sealing open pipe ends with 100 mm diameter
• Protecting housings and enclosures during transport or storage
• Temporary closure during maintenance and inspection
• Preventing contamination in assembly or installation phases

Key specifications

• Shape: circular cover
• Nominal diameter: 100 mm (D100)
• Primary function: dust and splash protection
• Application type: temporary or permanent sealing of openings
• Compatibility: intended for round openings with matching diameter

How to use

Align the cap with the opening so the sealing surface matches the edge of the pipe or housing. Press the cover onto the opening until it seats evenly and provides a visible seal. For removal, grip the cap at the outer edge and pull steadily to disengage. No specialized tools are required for standard installation and removal; if the fitting is tight, use an appropriate nondamaging lever or bar to assist while taking care not to deform the sealing surface.

Usage recommendations

Verify that the cap diameter matches the opening (100 mm) before installation. Inspect the sealing surface for damage or debris and clean the mating edge to ensure effective protection. For prolonged outdoor exposure or aggressive chemical environments, regularly inspect the cap for wear and replace if deformation or cracking is observed. Store spare caps flat in a dry area to maintain shape and prolong service life.
