Nitrile yana tura gasket na haɗin gwiwa don matsakaicin zazzabin sabis na digiri 150 Fahrenheit don aikace-aikacen ruwa da lambatu.

Neoprene (CR) (Polychloroprene)

Ana amfani da gaskets na Neoprene tare da bututun ƙarfe na Ductile yayin ma'amala da sharar mai. Amfani da su ya haɗa da:

Ruwan Sha; Ruwan Ruwa; Wankan Janaba; Maimaita Ruwa; Ruwan Ruwa; Ruwan Guguwa; Viton, Fluorel (FKM) (Fluorocarbon)

Waɗannan ana ɗaukarsu a matsayin “Mack Daddy” na kayan kwalliya na musamman - ana iya amfani da gas ɗin Viton don:

Hydrocarbons mai ƙanshi; Man Fetur; Man kayan lambu; Kayayyakin Man Fetur; Hydrocarbons mai sinadarin Chlorinated; Yawancin Chemicals da Solvents

Sauran ayyukan da aka yarda da su sun haɗa da:

Ruwan Sha; Ruwan Ruwa; Wankan Janaba; Maimaita Ruwa; Ruwan Ruwa; Ruwan Guguwa

Bugu da ƙari, Viton tura-kan haɗin gaskets suna da mafi girman matsakaicin sabis na digiri 212 Fahrenheit, yana mai da bututun Viton mafi kyawun duka da kuma keɓaɓɓun goge na musamman don bututun ƙarfe na Ductile. Amma kasancewa mafi kyau ya zo tare da tsada; wannan shine mafi tsada mai tsada a kasuwa.
