160×7 O Ring Seal Chemical Resistant For Fluid End Mud Pump GB3452.1-82 GB_T3452.1-1992

What is Φ160×7 O Ring Seal?

Φ160×7 O Ring Seal was used in Mud Pump Fluid End.

An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

What is the Φ160×7 O Ring Seal used for?

The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons.

Static applications of O-rings may include fluid or gas sealing applications in which: (1) the O-ring is compressed resulting in zero clearance, (2) the O-ring material is vulcanized solid such that it is impermeable to the fluid or gas, and (3) the O-ring material is resistant to degradation by the fluid or gas.

O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements. They have been tested to seal up to 5000 psi (35 megapascals) of pressure. The maximum recommended pressure of an O-ring seal depends on the seal hardness and gland clearance.

What are the sizes of Φ160×7 O Ring Seal?

O-rings come in a variety of sizes. Society of Automotive Engineers (SAE) Aerospace Standard 568 (AS568)[15] specifies the inside diameters, cross-sections, tolerances, and size identification codes (dash numbers) for O-rings used in sealing applications and for straight thread tube fitting boss gaskets. British Standard (BS) which are imperial sizes or metric sizes. Typical dimensions of an O-ring are internal dimension (id), outer dimension (od) and thickness / cross section (cs)

Metric O-rings are usually defined by the internal dimension x the cross section. Typical part number for a metric O-ring - ID x CS [material & shore hardness] 2x1N70 = defines this O-ring as 2mm id with 1mm cross section made from Nitrile rubber which is 70Sh. BS O-rings are defined by a standard reference.

The World's Largest O-ring was produced in a successful Guinness World Record attempt by Trelleborg Sealing Solutions Tewkesbury partnered with a group of 20 students from Tewkesbury School. The O-ring once finished and placed around the Medieval Tewkesbury Abbey had a 364m circumference (approx 116m id) and a cross section of 7.2mm.
