Check Valve Fitting

Teamco provides Check Valve Fitting in SS316 and AISI4140 (zinc plated) materials for hydraulic applications such as Oil&Gas piping system and industrial fluid control. The movable part to block the flow is a ball loaded by a spring to keep it shut. The check valve fitting allows flow moves in one direction and blocks the flow in the reverse direction. It means one-way flow, non-return or backflow prevention. It requires a higher pressure on the input side than the output side to open. When the pressure is higher on the outlet side (or is not high enough on the input side), it will close. Teamco produce check valve fittings in custom specifications and has been exporting to USA, Italy and other countries in South-East Asia such as Malaysia. They are applied to API applications in pressure class ranges 1,000 ~ 20,000psi. For achieving diversified applications and industry standards, materials and constructions can be produced according to customer designs.

  • Sealant Injection Fitting - Custom Injection Fitting fits Custom Specifications
    Sealant Injection Fitting

    Teamco provides Sealant injection fittings based on customer specifications to be used as valve backup sealing in applications of valve piping or industrial fluid control. The sealant injection fittings are primarily a one-way check valve designed to provide for the periodic injection of lubricant/ sealants into pipeline valves. The materials we produce include stainless steel, carbon steel and alloy. In Oil& Gas segment, most ball valves has two sealant injection fittings, generally one is located at the stem area and the other at the seat area. These sealant injection fittings only function for emergency or backup sealing when soft sealing rings damage by accident. In this situation the sealant is injected to prevent stem leakage and temporarily seal the valve. Our injection fittings apply to API requirements and are exported to worldwide oil&gas and industrial customers, such as USA, Canada, Italy and Malaysia, etc. All the specifications we produce are based on the customer designs. When receive the customer request, our product development team will be able to recommend or provide the best solutions fit customer’s diversified applications.

  • Grease Fitting - Custom Grease Fittings in Stainless Steel and Carbon Steel
    Grease Fitting

    Teamco manufactures grease fittings according to customer designs for purpose of mechanical system lubrication. The provided materials include carbon steels, stainless steels and alloys, depending on required mechanical strength and corrosion resistance level. Based on various ways of lubricating the grease or lubricant when using the grease gun, the grease fittings can be in giant button head or standard head. The main application of our grease fittings are valve part lubrications in the midstream segment of the oil and gas industry. Our grease fittings apply to API applications. Virtually every valve with moving metallic parts needs lubrication. Lubricants help to reduce valve operating torque. Periodic maintenance makes valves operate easier and seal properly. Small amount of the correct lubricant into the body or seat rings, fresh grease into the stem bearings, checking the stem packing and refilling as necessary will add years to the service life of the valve. We export to worldwide industrial customers in USA, Canada, Italy and Malaysia, etc. ODM and OEM are services which make us a trustworthy partner for customers.

  • High Pressure Grease Fitting - Custom High Pressure Grease Fittings fit Diversified Applications
    High Pressure Grease Fitting

    Teamco provides custom high pressure grease fittings achieve to 20,000psi. The body material we produce includes Inconel, Stainless Steel and Carbon Steel. Stainless steel usually provides high strength and good impact resistance over the various tempera¬ture ranges. The most popular applications for grease fittings are used in mechanical systems to feed lubricants, usually lubricating grease into a bearing under moderate to high pressure using a grease gun. The autoclave design provides metal to metal sealing. The spring, which is tempered with wire then coiled, cannot be compressed to restrict the flow of heavy lubricants or forced out of the body under normal pressures. Main applications of our high pressure grease fittings include oil & gas valve piping and industrial fluid control, etc. We export grease fittings to USA, Canada, Italy and other countries in South East Asia, etc.
