Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. They also compensate for large temperature fluctuations. Back up ring including BRT, N4W. Hydraulic cylinder seals prevent the leakage of working medium (internal and external leakage) and prevent foreign objects (such as air, dust and water) from entering the hydraulic components and hydraulic system.

Buffer seal is used in combination with rod packing to absorb the impact and fluctuating pressure at high load, to isolate high temperature fluid, and to improve the durability of the packing. The cylinder is cushioned and sealed, and the product itself has a pressure relief groove for easy exhaust. Robust design. Material: PU+Nylon; PTFE+Rubber+Nylon; PU; We have Original NOK Japan brand and other OEM brand.

O-ring is a rubber seal with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring and is also called an O-ring. It first appeared in the mid-19th century, when it was used as a sealing element for steam engine cylinders. O-ring specifications include UHSO-ring specifications, UHPO-ring specifications, UNO-ring specifications, DHO-ring specifications, piston rod O-ring specifications, high temperature O-ring resistance, high-pressure O-ring resistance, and corrosion-resistant O-ring Ring, wear-resistant O-ring. FKM and NBR with NOK brand and OEM brand.

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.
