seal manufacture

Rotary Seal are special seals mainly used for center joint of industrial equipment. Rotary Seal have excellent sealing ability and low friction.There are two main types of rotary seals for rotary joints, composite seals and mechanical seals. The composite material rotary seal is composed of two parts. It consists of an outer ring made of PTFE and an O-ring made of NBR. O-rings support the outer ring, making the entire rotary seal easier to install. Slide between the outer ring and the housing of the swivel joint.

The oil seal is a typical representative of the oil seal. Generally speaking, the oil seal refers to the oil seal. The skeleton is like the reinforcing steel in the concrete component, which strengthens and keeps the oil seal in shape and tension. According to the structure, it can be divided into single-lip oil seal and double-lip oil seal. Frame oil seal type TC, TC3, TB, HTC, HTC3, HTC5, HTC9, TCL, SCY, SCJY, VSB, VSB2, HTBW, HSC, TA, SA, SB, SC, CAP4, TCN, TCV, DKB, HTCL, EC, TBV, TG4.

The boned seal is a rubber ring and a metal ring integrally bonded and vulcanized, and is a sealing ring used to seal the thread and flange connection. The ring includes a metal ring and a rubber gasket. Anti-rust treatment of metal rings, rubber rings generally use oil resistant nitrile rubber or fluorine rubber. The combination pads are available in metric and inch sizes. There are standard JB982-77 regulations for the combination of metal pads and rubber in combination pads. Combination gaskets are used for threaded pipe joints and screw plugs. It is generally used with ferrule pipe joints to block oil ports. It is mainly used for static sealing of end faces of threaded joints of hydraulic valve pipe joints.
