JST Seals can provide vee packing manufactured from its range of high performance elastomers, PTFE and PEEK. Typical applications include mud pump packing, where the seal encounters high pressure and grinding media containing various solids, oil and water. 1. Test purpose The objective of this test procedure is to evaluate the quality of JST non elastic seal, V-Packing seal stack design as p...
Spgo seal, also known as glyd ring, is a low friction piston seal, which improves the perfect combination of sealing performance and service life by optimizing contact pressure and reducing the heat generated by friction. The D-section of this seal combines two special groove designs to maintain sufficient lubricating oil film between the seal and the contact surface, which can ensure sufficient f...
O-ring, also called O-shaped rubber ring, are used to prevent leakage and prevent external contaminants from penetrating the hydraulic system. It can be sealed within various pressure, temperature and tolerance ranges. It has small volume, light weight and can be reused. It has various sizes and materials to choose from. Product specification The size of the O-ring is determined by the inner diame...
Customer Question: Customer used a competitor 's S seal for 10000PSi and PU temperature classes. During installation at the Minden store, using a competitor's elastomer seal, the customer noticed some movement in the valve seat . Application details: Material: HNBR90+316SS Groove: 125 Groove size: 7.181X6.696X0.375inch How is the JST seal solv...
P seal is constructed from an elastomer with back up rings for anti-extrusion. Energized by the injection of sealant, it is a static seal that is used to seal rough casing and tubing. Backup rings are available in Mesh Stainless Steel or Solid Carbon Steel. The standard P Seal is a one-piece molded seal utilizing molded-in anti-extrusion device. This design enhances assembly by eliminating the loo...
Packer elements refers to a downhole tool seal connected to the downhole string and used to seal the annular space between tubing and oil and gas well casing or open hole wellbore. In oil production engineering, the packer is used for layering, and an oil production channel is designed on the packer. When setting, the piston sleeve goes up and the oil production channel is opened; After setting, t...
A correct installation can prolong the life cycle of the seal ring. We have following suggestions when install the spring energized seal. Preparation before installation: 1. Check whether the surface finish of the groove meets the requirements; 2. Clean the sealing ring and groove surface with dust-free cotton cloth; 3. Check whether the installation chamfer is smooth and free of burrs. Installati...
JST produces elastomer seal, material includes HNBR, NBR, FKM, AFLAS. There are lots of factors affecting an elastomer seal's performance, such as the chemical reactivity of the elastomer seal , working temperature, working pressure and working medium will influence the sealing performance. To make sure seal with no leakage and suitable for high temperature, lower temperature, high pressure, H2S/C...
Spring energized seal, also called spring loaded seal can select V-shape, H-shape or C-shape spring forms and sealing lip design according to various applications such as dynamic and static or internal and external pressure, so as to produce different sealing force and compressible deformation (see the following figure: spring deformation / elastic curve). The spring force will affect the performa...
