LP Classic Series

Proven Sealed-Skin hose for balanced everyday routing

Sealed-Skin Construction
LP Classic is built around a Sealed-Skin construction for dependable low-pressure use. Light weight, good flexibility, and solid layer cohesion define a compact structure built for stable service.

Balanced Handling
The series delivers an easy, controlled response in use, with straightforward routing and flex behavior that remains stable across standard layouts.

REGULATOR

For second-stage gas delivery, with 3/8” male UNF first-stage connection and 9/16” female UNF regulator-side fitting.

Color

Classic color range for low-pressure hose setups, with a clean satin finish.

  • Black
  • Yellow

Composition

Sealed-Skin construction built around a thermoplastic NBR outer coating, aramid reinforcement, and polyether-based polyurethane inner hose.

  • Reinforcement: High-resistance aramid fibres
  • Inner hose: Polyether-based polyurethane
  • Fittings: Nickel and chrome-plated brass

Oxygen & Nitrox Configurations

Configurable sealing and oxygen-service configurations for Nitrox-ready hose assemblies and controlled breathing-gas use.

  • +V: Viton O-rings for Nitrox-ready sealing upgrade
  • +O: O2 Clean preparation with oxygen-service cleaning and controlled assembly

Matte-black hardware for selected HYDPRO LP Hose Systems. A darker, lower-reflection fitting configuration built for clean technical hose routing, professional equipment integration, and reduced visual signature in low-visibility or mission-oriented diving setups.

Hose Systems. Series Engineering.

Pressure, flex, routing: no parameter works in isolation. From low to high pressure, each series is built around a distinct construction logic: materials, reinforcement, surface architecture and terminations work together to define pressure containment, flex response, routing stability and setup integration.
