Elastomer flange gaskets · EPDM, NBR, neoprene · ASME B16.21 · UAE stock
Rubber flange gaskets seal under very low bolt load, which makes them the usual choice for water, drainage and HVAC flanges, plastic and cast iron flanges, and pump connections.

An elastomer gasket fills flange surface imperfections with very little compression, so it seals well on flat-face cast iron, ductile iron, PVC and HDPE flange adaptors where high bolt torque would crack or distort the flange. Rubber is limited in temperature and pressure compared with fibre or metal gaskets, and it can extrude if over-tightened, so it is best kept to water and low-pressure utility service.
Hamza Fasteners supplies EPDM for potable water, chilled water and hot water, NBR for oils and fuels, and neoprene (CR) for general weather-resistant duty. Gaskets are available full face or ring, 1/2" to 24", for ASME Class 150 and PN10/16 flanges. Typical buyers are MEP contractors and water utilities. Request a quote from Dubai with sizes and medium.
