✨ Durometer hardness: It is a measurement of how stiff or soft an elastomer (elastic polymer) is. ✨ Durometer Scales and Seal Selection: There are actually multiple durometer scales, designated by letters (A-D). However, for elastomeric seals, the Shore A scale is predominantly used. It ranges from 0 to 100, with 0 being the softest and 100 being the hardest. ✨ Softer Seals (Low Durometer - Under 70A): ✅ Advantages: ◾ Conform better to uneven surfaces, creating a tight seal at low pressure. ◾ Offer good compression set resistance, meaning they retain their shape well over time. ❌ Disadvantages: ◾ More susceptible to wear and tear. ◾ Prone to extrusion in high-pressure applications (squeezing out of the seal groove). ✨ Medium Hardness Seals (Mid-Range Durometer - 70A to 90A): ✅ Advantages: ◾ Offer a good balance between conformability and wear resistance. ◾ Suitable for a wider range of pressures compared to softer seals. ❌ Disadvantages: ◾ Might not be ideal for highly uneven surfaces or very low-pressure applications. ✨ Harder Seals (High Durometer - Above 90A): ✅ Advantages: ◾ Provide excellent abrasion and tear resistance. ◾ Can withstand high pressures without extruding. ❌ Disadvantages: ◾ Less conformable, potentially leading to leaks at low pressures or on uneven surfaces. ◾ May generate higher friction, impacting efficiency. ✨ Seals play a crucial role in #HYDROSTATIC TEST & #ISOLATION PLUGS.
