O型圈的材料主要有丁氰橡膠NBR和氟橡膠FKM，氟橡膠更適用于高溫工況。除材料之外，O型圈很重要的一個指標(biāo)的是它的硬度，一般采用邵氏硬度來表示，從60到90左右不等，數(shù)值越大表示硬度越高。在同樣壓力下，硬度越高，防擠出(變形甚至撕裂)的能力就越強(qiáng)。因此，應(yīng)選用硬度較高的O型圈。然而，市場上常見的O型圈均為丁氰橡膠制成，邵氏硬度一般O型圈的溝槽設(shè)計有相關(guān)的國家標(biāo)準(zhǔn)，主要分動密封、軸向靜密封和徑向靜密封三種。法蘭、箱蓋等的O型圈采用軸向壓緊更便于裝配和保證密封性能。另外，我國國家標(biāo)準(zhǔn)中的溝槽尺寸標(biāo)準(zhǔn)已顯落后，如國家標(biāo)準(zhǔn)中受內(nèi)壓的O型圈溝槽外徑等于O型圈外徑，而PARKER法蘭接頭的O型圈溝槽外徑小于O型圈外徑。設(shè)計時應(yīng)適當(dāng)參考國外標(biāo)準(zhǔn)。在70左右，難以滿足相當(dāng)一部分工況的要求。有O型圈的密封面不得使用平面密封膠，可以在O型圈上涂少量黃油以使其不脫落。在維修時。

性能指標(biāo)1.分析項目：主成分分析、圖譜分析、失效分析、全成份分析、材質(zhì)鑒定、配方還原等2.物理機(jī)械性能：密度/比重、硬度試驗、表面電阻率、拉伸性能、沖擊性能等；3.老化性能：臭氧、紫外老化、鹽霧老化、氙燈老化、碳弧燈老化、鹵素?zé)衾匣?、壽命推算等?.耐液體性能：耐潤滑油、耐汽油、耐機(jī)油、耐酸、耐堿、耐有機(jī)溶劑、耐耐水性能等；5.燃燒性能：防火阻燃、垂直燃燒、酒精噴燈燃燒、巷道丙烷燃燒、煙密度、燃燒速率等；6.適用性能：耐液壓、脈沖試驗、導(dǎo)電性能、水密性、氣密性等。材料選擇用作O形圈的材料有丁腈橡膠、羧酸腈、氟橡膠、乙丙橡膠、氫化丁腈橡膠、硅橡膠、氯丁橡膠、氟硅橡膠、聚氨酯、氯醇橡膠、丁苯橡膠、丁基橡膠、天然橡膠、乙烯/乙丙酸橡膠、聚丙烯酸酯橡膠、全氟橡膠等等。同樣一種橡膠由于配方的不同，性能指標(biāo)也有較大的變化。所以在材料欄中簡單地填寫丁腈橡膠或丁腈-40是不準(zhǔn)確的。用于O形圈的材料化工部有專門的標(biāo)準(zhǔn)，如：HG/T2579-1994、HG/T2021-1991、HG/T2333-1992、HG/T3089-2001、HB5290-1991等。HG/T2579-1994專門去掉了材料的具體類別，只給出了材料的一些性能指標(biāo)。
