Three ball rubber joint
The three ball rubber joint is composed of rubber body and flange.
The rubber material of three ball rubber joint is NR / NBR / EPDM / PTFE. The rubber materials of the double sphere rubber expansion joint are suitable for different media, such as the EPDM with weak acid
and weak alkali. Flange material can be galvanized carbon steel,
painted ductile iron, stainless steel 304 / 316, etc.
Three ball rubber joint Performance characteristics
1.The three ball rubber joint could primarily reduce the quiver and the noise ofthe piping
system; completely solve the different piping problems
asdisplacement of jiont, axial flex and etc.
2.According to different material requirement,three ball rubber joint could be made as acid proof,alkali proof,corrosion proof to suit
different medium and environment.
3.The material of three ball rubber joint has good sealing performance, light weight, easy to fix and
maintain, and long service life. However, please keep away from
sharp metal to avoid steel ball breaking.

Note: 1. The special requirements of three ball rubber joint can be customized according to the user's drawing. Flange standard
is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB,
ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for
production. The rubber ball of three ball rubber joint can be used as natural rubber, ethylene propylene diene monomer
rubber, chloroprene rubber, butyl rubber, butadiene rubber,
fluorine rubber, etc. when the three ball rubber joint of DN200 and above is used for suspended water supply, the pipeline
must have fixed support or fixed support, otherwise three ball rubber joint should be installed with anti falling device.
