- 互いに連通する流体通路を有している一対の継手部材と、両継手部材の突合わせ端面の間に介在させられるシール手段とを備えており、いずれか一方の継手部材に設けられたおねじ部材と他方の継手部材に設けられためねじ部材とによって継手部材同士が結合されるとともに、スラストワッシャを含んだ共回り防止手段によってねじ部材と継手部材との共回りが防止されている流体継手において、
共回り防止手段は、2枚のスラストワッシャが重ね合わされることで形成されており、各スラストワッシャは、表面にNi−P+PTFE複合皮膜が形成されたステンレス鋼の熱処理品であり、各スラストワッシャの複合皮膜の厚みが4〜7μmとされていることを特徴とする流体継手。 - 共回り防止手段は、めねじ部材としての袋ナットに設けられており、袋ナットに、2枚のスラストワッシャを収納する環状の凹所と、凹所開口に設けられてスラストワッシャを脱落しにくくする爪とが設けられていることを特徴とする請求項1の流体継手。
- スラストワッシャは、円板状であることを特徴とする請求項1または2の流体継手。
- スラストワッシャは、円板状の一部が欠損したC状体であることを特徴とする請求項1または2の流体継手。
