- Deflash
- A process of removing unwanted, excess material (flash) from a finished product.
- Degassing
- Intentional, controlled outgassing of the volatile (evaporative) components of elastomeric materials.
- Diametrical Clearance
- The gap between the two mating metal surfaces forming a gland's internal cavity. Through slight oversizing and accompanying “squeeze,” the o-ring seals this gap to prevent system leakage.
- Durometer
- A measure of the hardness of a rubber compound. In a Shore A scale, the resultant numerical rating of hardness runs from lower numbered (30 or 40) softer materials to higher numbered (80 to 90) harder materials. Usually designated with a ±5 tolerance.
- Dynamic Seal
- Any application involving reciprocating, rotating, or oscillating motion relative to the seal.
