EPDM thawj O-rings

Raj Mis OD: 3/32 "

FDA / NSF Ua Raws Cai EPDM O-Rings:

Feem ntau siv nrog cov khoom noj, dej, cov ntaub ntawv siv zog, phosphate ester type hydraulic fluids, tso cov kua nruab nrog cev thiab muaj kev tiv thaiv zoo heev rau ozone thiab weathering. Sulfur-Cured FDA / NSF Qib EPDM yog tus nqi tsawg tshaj plaws thiab muab cov tshuaj tua tau zoo tshaj plaws thiab txhuam cov hnyuv tws dua ntawm Peroxide-Cured Systems. EPDM tsis siv nrog roj roj lossis cov roj hluav taws xob vim qhov o loj tuaj yeem ua rau.

Tshuaj Tiv Thaiv thiab Siv Tau:

Cov dej kub thiab tag nrho mus txog 300 ° F (149 ° C) nrog tshwj xeeb sib xyaw txog li 400 ° F (204 ° C)

Ntau cov dej / Cov Ntawv Siv Hauv Zos
