Methanol Quick Connector with double seal ring radial seal structure, rubber modified by O - ring, mainly for fluid and the physical, chemical properties of custom, prevent aging, corrosion, swelling; O - ring have intermediate spacer ring separated, two sealing rings of the corresponding event space, the rubber matrix bonding does not occur, the external O-ring using synthetic rubber, enhanced mechanical properties, prevent air aging. Sealing ring and a spacer ring through the outer ring of the elastic bayonet device firmly fixed in the shell, does not produce seal off and shift phenomenon produced. Greatly ensure the safety of the seal.

Methanol quick joint belongs to a fast joint, it can quickly assemble, without the tool. It can save time, reduce the cost, and can realize the characteristics of automatic assembly, it is mainly suitable for automatic production line.
