Hydro Testing Seals

Naval Auto Industries Pvt Ltd > Hydro Testing Seals

High-Performance Seals for Hydrostatic Tube Testing Machines

We manufacture premium-quality hydro testing seals specifically designed for use in tube testing machines operating under demanding hydrostatic pressure conditions. These fully moulded polyurethane seals are engineered to repeatedly seal and release steel tube ends during the hydrostatic testing process without performance degradation.

Seal quality is critical to the reliability and efficiency of hydrostatic tube testing systems. Our tube test seals are manufactured to deliver maximum durability, pressure resistance, and operational consistency.

What Are Hydro Test Seals?

Hydro testing seals are specialised sealing components used in hydrostatic pressure testing machines to temporarily seal steel tube ends while internal pressure is applied to verify structural integrity.

These seals must withstand:

  • Repeated sealing and release cycles
  • Extremely high pressures
  • Abrasive and mechanical stress
  • Harsh industrial environments

Our fully moulded polyurethane hydro test seals are engineered to meet these demanding requirements.

Applications

Our hydrostatic testing seals are widely used in:

  • Steel tube and pipe manufacturers
  • Oil & gas pipeline production
  • Pressure vessel testing
  • Heavy industrial manufacturing
  • High-pressure engineering facilities

Key Features of Our Tube Testing Seals

  • Fully moulded precision construction
  • High tensile, impact-resistant polyurethane material
  • Excellent wear resistance for extended service life
  • Operates effectively at both high and low pressures
  • Special lip profile for smooth tube entry without seal damage
  • Proven reliability in continuous production environments

Dual & Single Hardness Hydro Test Seals

We offer both single hardness and dual hardness hydro testing seals to suit different testing conditions and pressure regimes.

Dual Hardness Seal Advantages

  • Enhanced anti-extrusion performance
  • Improved durability under high pressure
  • Longer operational lifespan
  • Greater tolerance of poor mechanical alignment
  • Improved resistance to deformation
All seals are colour coded for easy identification based on test heads or operating pressures.

Custom Manufactured Hydro Test Seals

We manufacture custom hydro testing seals in any size and quantity to meet your specific machine requirements.
  • Custom dimensions available
  • Low to high production volumes
  • Large inventory of moulds covering most industry standards
  • Fast turnaround times
Whether you operate a high-pressure hydrostatic testing facility or a standard tube testing line, we can supply precision-engineered seals to ensure optimal machine performance.

Operating Capability

Our hydrostatic tube testing seals are regularly used at:

  • Operating pressures exceeding 100 MPa (14,500 psi)
  • Thick-walled, high-pressure rated steel tubes
  • Continuous high-cycle testing applications

Designed for extreme pressure sealing, our polyurethane seals maintain integrity even under severe load conditions.
