Moulding – our dln method of ‘O’ ring manufacture Moulding produces the highest integrity seals Over 10, mould tools in our inventory Non-stocked tools rapidly made to specification Press capacity for precision moulding of endless ‘O’ rings up to 2. Suitable for diin and cold water, ammonia, ethylene glycol, dilute acids and alkalis. We will swiftly produce any size of non-standard ‘O’ ring you need by using one of the three following techniques.

And this service is free of charge 5.

We have been making top-quality ‘O’ rings since this sealing method dij introduced in the s. Sealing applications are limited by gas permeability, low tensile strength and low abrasion resistance.

They should be used: Recommended for mineral oils – particularly hydraulic fluids – water and some solvents. The first time business corporation,how can I trust vin Where fluid pressure exceeds bar Where low strength O’ rings are installed Where adverse mechanical conditions prevail If the application is double-acting, use two back-up rings – one on either side of 33771-1 seal in its housing groove But contact James Walker for technical advice if fluid pressure is likely to exceed bar.

We recommend that back-up rings are installed to prevent the extrusion of an ‘O’ ring seal in its housing groove under certain operating conditions. Dynamic seal pressure should less than 5MPa.


We have buyer assistants who speak English Non-standard ‘O’ rings for static duties only Ends of an extruded cord are vulcanised together in a mould to form an endless ring 3mm minimum section diameter mm minimum ID of ‘O’ ring.

Virgin PTFE and a wide range of filled materials are processed in-house. If we have stock ,we will send out in 2days after we receiving your freight account or freight fee.

We manufacture and stock ‘O’ rings in numerous size ranges including: We manufacture and stock a wide range of elastomeric ‘O’ ring cord. Packaging Details less than by the plastic 37771-1, more than by the carton; or as the customer’s demands.

Applications ranging from garden hose couplings to critical aerospace duties make it the world’s most popular volume produced seal. How long can I get the sample? We have year experience specialize in rubber sealing, we are professional. The development, processing and application of fluid seal materials are James Walker specialities.


The humble ‘O’ ring is an exceptionally versatile sealing device. Today we hold a vast range of stock sizes and materials for same day despatch sin and back this with an emergency manufacturing service to supply you any items that we do not have immediately available.

Good service with many media on static sealing duties. All the components we specify and supply are manufactured by DuPont Dow Elastomers.

Static seal pressure should 33771-1 than 20MPa. How will the goods send to me? Silicone VMQ – Good resistance to heat, weathering and compression set at high temperatures, plus excellent electrical properties. Welcome to visit Shanghai youqi sealing technology co. For mass production,can dinn by air or by sea. The more details you provide,the more accurate price you will get,and of course,if some details you are not sure,just tell us and we will provided our optional list for you.
