Bonded Seals – Dowty Seals

A Bonded (Dowty) Seal, is a washer with a rubber gasket bonded to a metal outer ring, used to provide a leak-free seal around a bolt or screw. It consist of a metal outer ring and a rubber inner ring vulcanized together. Leak-Proof and Cost-Effective solution for high-pressure applications. Widely used in Automotive, Hydraulic, and Industrial Applications to Seal joints and prevent Contamination.

Precision Under Pressure - ALIF's Engineered Approach to Leak-Free Hydraulics

Problem Statement and Challenges in Hydraulic Fitting Implementations

The primary problem in hydraulic systems is frequent leakage, which can lead to equipment downtime, wasted fluid, safety accidents, and environmental pollution (p. 1).

Key challenges that cause these failures include:

  • Fatigue and Vibration Damage: Continuous, insufficiently isolated vibrations in rigid connections can cause alternating stress, metal fatigue, and transverse cracks in fittings (pp. 2-3).
  • Pressure Miscalculation: Impact pressure (water hammer effect) or simply exceeding the working pressure without considering an adequate safety factor can lead to hose bulging and bursting (p. 4).
  • Incompatibility and Corrosion: Incompatibility between the hydraulic fluid and the hose's inner rubber layer can cause swelling, peeling, deterioration, and contamination of the entire system (p. 4).
  • Installation and Stress Issues: Improper installation practices such as an excessively small bending radius, lateral tension, or torsion can generate high local stress and shorten the lifespan of the pipeline (p. 4).
  • Design Deficiencies: Incorrect design of connections, improper selection of sealing ring materials, or lack of adherence to standards like ISO and GB can lead to inherent leakage issues (p. 4).

Solutions and Practices

ALIF's Hydraulic Fittings product-approach proactive design and maintenance through methods such as:

  • Enhanced Fatigue Resistance: Increasing the wall thickness of steel pipe fittings (p. 5).
  • Using Flexible Connections: Replacing rigid pipes with high-pressure rubber hoses to absorb shock and vibration (p. 5).
  • Scientific Selection: Calculating the correct pipe diameter and ensuring the hose working pressure is at least four times the minimum burst pressure (p. 5).
  • Standardized Installation: Adhering to minimum bending radii, using proper clamps, and avoiding friction (p. 5).
