Section 1: The Structural Value of This Handbook Is a Set of "Sealing Engineering Workflow" The handbook's organization method is very worth replicating. It expands step by step from O-ring definition, sealing principle, groove design, dimension sta...

What is most worth Chinese enterprises learning from the ERIKS O-ring Technical Handbook is that it truly builds sealing parts into a business — not just selling rubber rings, but selling an "application package." The handbook discusses O-ring...

Low temperature causes rubber to gradually transition from a highly elastic state to a delayed elastic, glassy or locally brittle state; simultaneously the O-ring thermal shrinkage, rebound slowing, and insufficient compression recovery cause the se...

O-rings in semiconductor equipment are not "ordinary sealing parts," but the superposition of process contamination control, vacuum maintenance, chemical compatible parts, plasma consumables and traceable quality. Ordinary industrial scenarios mainl...

Vacuum sealing O-rings cannot be selected only by "material + dimension + hardness." Under vacuum operating conditions, sealing failure is often not simple leakage, but a gas load formed jointly by true leakage, rubber permeation, material outgassin...

FEP/PFA-encapsulated O-rings are more suitable for scenarios where the media is very corrosive, but the seal still needs elastic compensation; solid PTFE O-rings are more suitable for scenarios that are static-seal only, groove easy to install, comp...

1. Why Are Dust, Mud, and Abrasive Particle Environments Especially Unfriendly to O-Rings The O-ring essentially relies on elastic compression deformation to produce contact pressure sealing. It is suitable for static seals, low-speed reciprocating ...

O-rings "can" do rotary sealing, but should usually not be the first choice for continuous rotary shaft sealing Let's first clarify a key point: if the O-ring is installed at an end cover, flange, housing, plug and similar position, and there is no ...

1. Hot Water: Priority Peroxide-Cured EPDM The core risk of hot water operating conditions is not "chemical corrosion," but long-term high-temperature compression set, hardening, precipitates, aging, and installation stress. For ordinary cold water...
