Component Specifications

Definition
A Gasket/O-Ring is a precision-engineered sealing component specifically designed for terminal heads in industrial machinery. It creates a static or dynamic seal between mating surfaces to prevent leakage of fluids (liquids or gases), exclude contaminants, and maintain pressure integrity. In terminal head applications, it ensures reliable connections in hydraulic, pneumatic, or fluid transfer systems by compensating for surface imperfections and thermal/mechanical variations.
Working Principle
Works on compression sealing principle: when compressed between two surfaces, the elastomeric material deforms to fill microscopic gaps and irregularities, creating a barrier against fluid/gas passage. For dynamic applications, it maintains seal through controlled interference fit and material resilience.
Materials
Nitrile rubber (NBR) for oil resistance, Fluorocarbon (FKM/Viton) for chemical/temperature resistance, Ethylene Propylene Diene Monomer (EPDM) for steam/weather resistance, Silicone for food-grade applications, Polyurethane for abrasion resistance.
Technical Parameters
  • Hardness 70-90 Shore A
  • Inner Diameter 5-500 mm
  • Pressure Rating Up to 3000 psi (static), 1500 psi (dynamic)
  • Temperature Range -40°C to 200°C (material dependent)
  • Cross-Section Diameter 1-10 mm
Standards
ISO 3601, DIN 3771, AS 568A, JIS B 2401

Engineering Analysis

Risks & Mitigation
  • Chemical incompatibility causing swelling/degradation
  • Improper installation leading to extrusion/nibbling
  • Thermal degradation exceeding material limits
  • Compression set reducing sealing force
FMEA Triads
Trigger: Chemical incompatibility with system media

Frequently Asked Questions

What's the difference between gaskets and O-rings for terminal heads?

Gaskets are typically flat seals for static applications between flanges, while O-rings are toroidal seals for both static and dynamic applications in grooves. Terminal heads often use O-rings for radial sealing in ports.

How often should terminal head O-rings be replaced?

Replace during scheduled maintenance (typically 1-3 years) or immediately if signs of compression set, cracking, swelling, or leakage appear. Frequency depends on operating conditions and material compatibility.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
