A: We are a factory located in Dezhou, Shandong, China.     If there is the opportunity, welcome all interested customers to visit our factory .Q: Can I purchase in small quantities?A: Our products adopt a tiered quotation method.       You could check the quantity and corresponding price you need in the product link you are interested in.Q:Do you accept OEM orders?A: We accept it.     If customization is required, customers need to provide the corresponding drawings and specific parameters

We have our own product quality testing laboratory, which can independently conduct a variety of quality testing experiments and issue test reports. Specific testing items are: hydrochloric acid spray destructive test, slot test, bushing bore accuracy test, and hardness test, etc.

1. We have our own factory, rich production experience, and independently produce and sell2. Provide competitive prices while ensuring high and stable qualityIn the entire production process, PengTuo has strict control over quality, from blanks to semi-finished products to finished products, and each link has corresponding inspection items. For example, we will conduct preliminary precision measurements after the initial grinding is completed; after the processing is completed, dynamic balancing tests and other tests are performed.3. Partial standing inventory and accurate delivery timeDifferent models and quantities have different delivery times. Generally speaking, for some standard models with high sales, we have standing inventory, and the delivery time is generally 7-10 days Standard models with small purchases generally have a delivery time of 20-30 days. For large purchases or customized models, it is generally 40-50 days.4. Strict production processStrict production processes can ensure the accuracy of delivery dates. After receiving the order, we will strictly convey the production requirements to the factory according to customer needs, schedule reasonably, and ensure that the products are shipped on time within the delivery period.5. Stable production capacityThe machine tools in the factory are all CNC high-precision machine tools.High-precision CNC lathes processed precise turning and grooving of blanks according to the set parameters High-quality production tools not only ensure product quality, but also improve our supply capacity.

AFT design and manufacture HPHT gate valve seat seals for valve manufacturers worldwide. Typically these comprise an AF801 Victrex™ PEEK jacket energised with an Elgiloy® spring with a PTFE insert to prevent permanent deformation of the seal and spring should something go wrong.

AFT manufacture a wide variety of high pressure high temperature high performance valve stem seal assemblies and gland packings. None of these are standard although many follow a standard theme. Featured here is an example of a high pressure gate valve stem seal assembly, tested at 15000 PSI and -29°C to +180°C.

Our team can design and manufacture custom seals on a range of materials to suit your application. Tell us about your requirements and one of our specialists will be in touch.

These products are extremely versatile and somewhat modular. The V-ring can be made in PEEK, filled PTFE or even an elastomer for certain applications. They can be designed with more than one V-ring in each stack and they don’t have to be the same material to improve lower and higher temperature performance.

Learn more about our CNC milling capabilities and how we can help bring your ideas to life. Our expert team is ready to take on your next project. We offer comprehensive plastic CNC milling services from the micro in size to much larger 1 meter long components.

We pride ourselves on our expert knowledge of the compressor parts industry, providing a wide range of compounds suitable for your application.

With outstanding mechanical, thermal and chemical resistance properties, PEEK is an ideal material to use for sealing applications.

Whilst we work around typical designs and groove dimensions for much of what we do, it is not a full picture of all we do. Many of the seals we design and supply are specials – the difficult applications, the extremes, often specific to particular products and service conditions and very often oil and gas related.

AFT Fluorotec have an extensive range of PTFE materials and we can also produce seals in other materials such as VICTREX® PEEK, PU, FPM and NBR.

We provide a bespoke fluoropolymer component design & manufacture service and can deliver the right solution to your problem.

When you’ve tried standard profile seals without success or know you’re going to need a bespoke solution for a particular project, we can deliver what you need.

CNC turning of PTFE and engineering plastics. Live tooling on our lathes mean competitive pricing and shorter lead times.

From back up rings and mining seals to piston seals and o rings, we offer a wide range of sealing products machined from polytetrafluoroethylene (PTFE).

All of our spring energised rod and piston seals are available as face seals however certain extreme applications require extreme seals.

This means that even after an episode of rapid decompression, the seals will perform as normal. These high performance face seals are not limited to gate valves. They can be used in any extreme applications where a high performance semi static seal is required.

The transmission products we sell have a very wide range of applications and adaptation equipment, such as central air-conditioning systems, industrial fan systems, agricultural machinery, oil extraction machinery, mining machinery, etc.

Pulley Data: We are a factory that produces transmission parts. Our main products are pulleys, taper bushing, synchronous pulleys, welded hubs, etc. V belt pulley specifications: European standards :   1) Pulley : SPA, SPB, SPC, SPZ  2) TB Bushing: 1610, 2517, 3020, 3535, etc. American standard:       1) Pulley: AK, BK, 3V, 5V, 8V          2) QD Bushings: H, SH, SDS, SK, SF, M, N, etc. Most of our products are made of cast iron, and we could also use other materials according to customer needs. We have mature surface treatment processes, the most common of which are phosphating blackening and electrophoresis. The maximum diameter we can produce is 1.6 meters.

Our inspection and measuring equipment includes a state-of-the-art CNC Coordinate measuring machine, and optical measuring machines.
