🔬 Deep Technical Specifications of Rubber O-Ring

This section focuses on the core technical engineering aspects that define the performance, reliability, and durability of RUBBER-KU Rubber O-Rings.

---

📐 1. Dimensional Standards & Tolerances

RUBBER-KU O-rings are manufactured according to international standards:

• ISO 3601
• DIN 3771
• JIS B2401
• AS568 (USA standard)

📏 Key Dimensions:

• Inner Diameter (ID): Defines fit on shaft or piston
• Outer Diameter (OD): ID + 2 × Cross Section
• Cross Section (CS): Thickness of O-ring

🎯 Tolerance Control:

• Precision tolerance based on ISO 3601 Class A/B
• Tight dimensional accuracy ensures:
  • Proper groove fit
  • Uniform sealing pressure
  • Reduced leakage risk

---

⚙️ 2. Compression (Squeeze) Engineering

Compression is the most critical factor in O-ring sealing performance.

✔️ Recommended Compression Rates:

• Static Seals: 20% – 30%
• Dynamic Seals: 10% – 20%

⚠️ Engineering Considerations:

• Under-compression → leakage
• Over-compression → excessive wear & friction

📊 Compression Formula:

• Compression (%) = (CS – Gland Depth) ÷ CS × 100

---

🧩 3. Gland (Groove) Design Parameters

Correct groove design ensures optimal sealing efficiency.

📐 Key Parameters:

• Gland Depth → Controls squeeze level
• Gland Width → Allows expansion under pressure
• Gland Fill → Should not exceed 85%
• Clearance Gap → Prevents extrusion

🔧 Surface Finish Requirements:

• Static: Ra 1.6 – 3.2 µm
• Dynamic: Ra 0.4 – 0.8 µm

---

🧪 4. Material Hardness & Mechanical Properties

🧱 Hardness (Shore A Scale):

• 30–50 → Soft (low pressure, high flexibility)
• 60–70 → Standard industrial use
• 80–90 → High pressure, extrusion resistance

📊 Mechanical Properties:

• Tensile Strength → Resistance to breaking under tension
• Elongation at Break → Flexibility before failure
• Modulus → Resistance to deformation
• Tear Resistance → Resistance to crack propagation

---

🌡️ 5. Temperature Performance Limits

Temperature directly impacts elastomer behavior:

Material	Min Temp	Max Temp
NBR	-30°C	+120°C
EPDM	-50°C	+150°C
Silicone	-60°C	+200°C
Viton (FKM)	-20°C	+250°C

🔥 Thermal Effects:

• High temp → softening, compression set
• Low temp → hardening, loss of elasticity

---

🧴 6. Chemical Compatibility & Swelling Index

Chemical exposure affects elastomer stability.

✔️ Key Technical Factors:

• Volume Swell (%)
• Mass Change (%)
• Hardness Variation

🧪 Compatibility Overview:

• NBR → oils, fuels
• EPDM → water, steam
• Silicone → neutral chemicals
• FKM → aggressive chemicals, solvents

---

⚙️ 7. Pressure Resistance & Extrusion Control

📊 Pressure Capability:

• Standard O-rings: up to 25 MPa (250 bar)

❗ Extrusion Risk Factors:

• High pressure
• Large clearance gaps
• Low hardness materials

🔧 Engineering Solutions:

• Use backup rings
• Increase hardness (Shore A)
• Optimize groove clearance

---

🔄 8. Dynamic Sealing Technical Factors

Dynamic applications require advanced considerations:

✔️ Friction Coefficient

• Influences wear and energy loss

✔️ Lubrication

• Reduces heat generation and wear

✔️ Surface Speed Limits

• High speed → increased wear risk

✔️ Wear Resistance

• Depends on material formulation and hardness

---

🧬 9. Compression Set & Elastic Recovery

📊 Compression Set Definition:

Permanent deformation after prolonged compression.

✔️ Ideal Performance:

• Low compression set = better long-term sealing

🧪 Test Standard:

• ASTM D395

---

⚠️ 10. Failure Mode Technical Analysis

❌ Extrusion (Nibbling)

• Cause: high pressure + clearance
• Solution: backup rings

❌ Compression Set

• Cause: heat + time
• Solution: high-quality materials

❌ Chemical Attack

• Cause: incompatible fluid
• Solution: proper material selection

❌ Abrasion Wear

• Cause: dynamic movement
• Solution: lubrication + proper hardness

---

🏭 11. Manufacturing & Quality Control Standards

🔧 Production Methods:

• Compression molding
• Injection molding
• Transfer molding

🔍 Quality Testing:

• Dimensional inspection (ISO 3601)
• Hardness testing (Shore A)
• Tensile & elongation testing
• Compression set testing
• Chemical resistance testing

---
