Cable Seals Lightwin DC 10MM SEAL 3.8MM

The Lightwin Cable Seals DC 10MM SEAL 3.8MM provide a compact sealing solution for round cables and connectors where moisture resistance and secure mechanical fit are required. Designed by Lightwin, these cable seals fit 3.8 mm cable diameters and mate with 10 mm style connector openings. They are supplied in assorted colors and rated to withstand a maximum water pressure of 0.5 bar, helping to prevent water ingress and extend cable service life in exposed environments.

Advantages

These cable seals combine a slim profile with resistance to light water exposure, offering a reliable barrier against moisture at connector interfaces. The assorted color options support visual identification and organization. The design emphasizes ease of installation while maintaining a secure mechanical grip around a 3.8 mm cable, and the 0.5 bar water pressure rating indicates suitability for applications with limited exposure to wet conditions.

Suitable for

• Sealing round cables with nominal diameter around 3.8 mm
• Use with 10 mm connector openings or housings
• Indoor and sheltered outdoor connections with occasional moisture exposure
• Color-coding of cable runs or connection points

Key specifications

• Cable nominal diameter compatibility: approximately 3.8 mm
• Connector opening compatibility: 10 mm style
• Maximum water pressure resistance: 0.5 bar
• Color: assorted
• Primary function: cable sealing to reduce water ingress

How to use

Insert the cable through the seal so the sealing lip engages around the cable jacket, then push the seal into the 10 mm connector opening or housing until it seats fully. Confirm the seal is aligned and that the cable remains centered in the opening to ensure an effective barrier against moisture. For multi-cable installations, use the assorted colors to maintain clear identification of individual lines during assembly and maintenance.

Usage recommendations

Verify cable outer diameter before installation to ensure compatibility with the 3.8 mm seal. These seals are intended for applications with limited water exposure (up to 0.5 bar); they are not rated for prolonged submersion or high-pressure washdown. Periodically inspect seals in outdoor or variable environments and replace if signs of wear, deformation, or compromised sealing are observed.
