(1) Classification by Contact & Position

1. Contact Seal vs. Non-Contact Seal (based on interaction with moving parts)

2. Circumferential Seal (radial sealing) vs. End Face Seal (axial sealing, also called Mechanical Seal)

3. Note: Centrifugal & spiral seals (in dynamic seals) utilize fluid motion for sealing and are sometimes termed Power-Activated Seals.

(2) Static Seals

1. Three Main Types:

1) Gasket Seals

2) Sealant (Liquid/Gel) Seals

3) Direct Contact Seals

2. Pressure-Based Subtypes:

1) Medium/Low-Pressure: Soft, wide gaskets (e.g., rubber, compressed fiber)

2) High-Pressure: Hard, narrow metal gaskets (e.g., copper, steel)

(3) Dynamic Seals

1. Rotary Seals (for rotating shafts, e.g., oil seals, lip seals)

2. Reciprocating Seals (for linear motion, e.g., piston seals, rod seals)
