Products Description

BCD LP hose O-rings are sealing components designed specifically for low-pressure hoses of diving buoyancy control devices. They are manufactured using high-precision technology to ensure airtightness and durability and to safeguard the stability of underwater breathing and buoyancy regulation.

Advantages

High Sealing Performance

Made of elastic materials (such as nitrile rubber and fluoro rubber), it can fit tightly into the interface gap and effectively prevent gas leakage.
The cross-section of the O-ring is circular, and it deforms evenly when under pressure, which can adapt to connectors with different tolerance ranges.

Pressure and Corrosion Resistance

Designed for low-pressure gas circuits (usually <30 bar), it can withstand water pressure changes at diving depths.
Resistant to chemical corrosion from seawater, salt spray, lubricating oil and gas, extending service life.

Low Maintenance Cost

Low cost, but directly affects equipment reliability, and is a key spare part with extremely high-cost performance.

Temperature Adaptability

Most materials can maintain elasticity from -20°C to +100°C, suitable for cold water or tropical diving environments.

Functions

1. Ensure air circuit sealing
A seal is formed at the interface between the BCD inflation valve, low-pressure hose, and regulator to ensure stable gas delivery to the BCD airbag.

2. Maintain stable air pressure
Prevent accidental gas leakage during exhaust operation to ensure that the BCD airbag adjusts its volume as needed.

3. Long-term stability
Compensate for interface wear or vibration through elastic deformation to reduce the risk of failure caused by equipment aging.

4. Redundant safety protection
As the first line of defense for the air circuit system, it prevents small leaks from developing into serious failures.

Features

Material Characteristics

Nitrile rubber (NBR): economical and practical, excellent oil resistance, suitable for conventional diving environments.
Fluororubber (FKM/Viton): more resistant to high temperatures and chemicals, suitable for extreme environments or high-purity gases.
Silicone: good low-temperature elasticity, but slightly inferior wear resistance, needs to be selected according to the scene.

Compact Design
Small size (usually diameter <10mm), does not take up extra space, suitable for compact diving equipment.

Standardized Specifications
Manufactured according to international standards (such as AS568), strong versatility.

Both Dynamic and Static Sealing
Can be used for fixed interfaces (static sealing) and slightly movable connectors (dynamic sealing).
