Product Description

   Bonded washers are made of rubber loops and metal rings as a whole by vulcanization. They are used to seal the sealing ring of threads and flanges. It consists of a metal ring and a rubber gasket.Metal ring through the anti-rust treatment, rubber generally use oil nitrile rubber or fluorine rubber.The combination pad has both metric and imperial sizes.

Technical data
operating pressure: ≤40 Mpa
temperature: -25ºC~ 100ºC
medium: hydraulic oil

Usage instructions
   apply to oil as the medium in the pipeline system, for welding, card sets, expanding pipe joints, plugs and pressure system sealing mechanism to prevent oil, fuel, water, medicine and other leaks. Because of its simple structure, high efficiency, and low cost of sealing, which is widely used in manufacturing.

Product details

Material	Low TEMP.	High TEMP.	Performance
NBR	-40	125	Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters.
HNBR	-25	140	HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties.
ACM	-25	150	It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance.
EPDM	-40	125	Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler.
VMQ	-60	225	The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance.
FKM	-20	250	Excellent chemical resistance except ester and ketone.
