Product description
UML PRV Oral Inflation Tube – Manual Control You Can Trust
The UML PRV Oral Inflation Tube provides a dependable manual inflation solution for lifejackets and buoyancy aids, giving users precise control when it matters most—during emergencies and routine servicing alike.
Certified to CEN/ISO 12402-7, this oral inflation tube integrates a built-in pressure relief valve (PRV) to help manage internal bladder pressure while maintaining consistent airflow and safe operation in demanding marine environments .
Available in 100mm length, the UML PRV Oral Inflation Tube delivers robust airflow performance, intuitive operation, and long-term durability, manufactured from high-grade, marine-proven materials engineered to perform across extreme temperatures and high-humidity conditions.
A pressure-release (PRV) oral tube
When bladder pressure reaches a set limit (Nominal Pressure Relief Setting of 3.5 psi), the PRV automatically vents excess air. You can keep blowing, but the jacket won’t keep pressurizing beyond its safe design limit. The result is controlled buoyancy, protected materials, and far less chance of damage from over-inflation.
What that actually means in the real world:
-
You can’t over-inflate the bladder through the oral tube
-
Internal seams and welds are protected from stress
-
Bladder shape stays closer to its certified buoyancy profile
-
Manual inflation is safer during emergencies, when people blow harder than they think
-
Maintenance and service inflation is more repeatable and less risky
