Products Description

Underwater strobe light rubber O-rings are a kind of sealing component specially designed for underwater photography equipment. They are mainly used to prevent moisture from penetrating the flash light and protect delicate electronic components from water pressure and corrosion.

Application Advantages

Good Waterproof Seal

The precisely designed ring structure fits tightly to the device interface, effectively isolating moisture, sand, and impurities from penetrating and preventing the internal circuits and components of the device from being damaged by moisture.

Corrosion and Aging Resistance

The material can withstand erosion by seawater, salt water, ultraviolet rays, and ozone, and remains elastic even after long-term immersion or exposure to outdoor environments, extending its service life.

High and Low-Temperature Adaptability

The operating temperature range is wide (-40°C to +200°C), adapting to extremely cold deep sea or tropical waters, avoiding deformation or failure due to temperature changes.

Compression and Shock Absorption

The elastic buffer design can absorb equipment vibration and external impact, protect the precision components of the strobe light, and reduce the risk of failure.

Functions

Core sealing barrier: Underwater strobe light rubber O-rings can prevent water pressure penetration, ensure the dryness of the inside of the strobe light, and ensure the safety of electronic components.

Pressure balance: Automatically adjust deformation in deep water and high-pressure environments to maintain stable sealing performance.

Compatibility and adaptation: Accurately match the interface size of strobe lights of different brands (support customized specifications), and adapt to various connection methods such as threads and buckles.

Extend equipment life: Reduce short circuits and oxidation problems caused by water seepage, and reduce maintenance frequency and costs.

Material characteristics

1. Main Material:

Using fluoro rubber (FKM) or silicone, two options to meet different needs:

Fluororubber: ultra-high chemical resistance, oil resistance, acid, and alkali resistance, suitable for industrial-grade underwater equipment or polluted waters.

Silicone: non-toxic and environmentally friendly, excellent flexibility, outstanding high and low-temperature resistance, suitable for photographic precision equipment.

2. Surface Technology:

Smooth burr-free design to reduce friction loss; some models add anti-microbial coating to inhibit algae attachment.

3. Environmental Certification:

Complies with ROHS and REACH standards, safe for use in marine ecological sensitive areas.
