Whether you're a buyer or a design or product engineer, ZSi-Foster can meet your need for:

  • Flow performance

  • Debris-free cleanliness
  • Material compatibility
  • Price
  • Availability

Looking for a wide range of product in different sizes? At ZSi-Foster we keep them in stock, avoiding long lead times which could set you back.

Maybe you need a lock-out mechanism to prevent accidental disconnect or a collar to prevent a user from moving the sleeve to disconnect. ZSi-Foster is your one-stop shop.

Every day food & beverage, medical, and pharmaceutical companies count on ZSI-Foster to keep their operations running smoothly

ZSi-Foster began serving the food & beverage industry 40 years ago, beginning with the Straight-Thru FST Series. We were first to market with this product.

More recently, our team began serving the medical and pharmaceutical industries offering the FHK Series. The FHKs incorporate valves in both socket and plug halves to prevent fluid loss when the socket is disconnected.

Our high-quality, high-performance FDA-approved seals and quick disconnect products are designed to do what you need them to do. For example:

  • Need flow performance, minimal pressure drops or a high level of cleanliness? ZSi-Foster can meet your requirements and high standards.

If you have a media or lubricant that requires a particular seal, we can ensure you get properly outfitted to prevent debris, contamination, or blockage.

We also improve locking with:

  • Stainless Steel Locking Balls, which offer a unique configuration engineered to lock two halves together. Drilling our locking balls at a slight angle allows for more contact area on the ball, which means the product cannot disconnect.
  • Try this quick test demonstrating the superior quality of ZSI-Foster's locking balls compared to the competition's product:
  • Take a competitor's socket and shake it. You'll hear the balls feely moving and rotating inside. Now shake a socket containing ZSi-Foster locking balls. There's no noise because the locking balls are well-matched to the body and material. This is ZSI-Foster innovation at work.
  • The FHK Series incorporates valves in both socket and plug halves for minimal fluid loss when the socket is disconnected. Available in 1/8" to 1" the FHK Series features radiused holes for the locking balls, which deliver greater wear resistance and a longer coupling life.
  • As an added bonus, the FHK Series can hold a minimum 27" Hg for two hours with no evidence of vacuum decay.

Our team of professionals is reliable, quick to respond-and able to provide the support you need to meet FDA regulations. If it's simply a smaller footprint you need, our engineers can work with you to design a product to meet your unique specifications.

Here's something else you may be surprised to learn about ZSI-Foster

We offer products in a variety of different materials such as brass, nickel-plated brass, or stainless-steel grade 303, 304, 316, or better.

Our products also come in a variety of finishes such as chrome-plated or with a colored powder coating on the outside. If you don't see it, ask us.

Need extra help resolving a problem?

The ZSi-Foster team responds to you personally. When you call you reach a real person who can discuss your specific challenges and answer your questions.

Need a particular configuration on a product? We can help. In one case, we helped a food and beverage customer prevent debris from getting caught in their deep fryer and blocking flow by configuring a 2-legged valve to replace a 3-legged valve.

In the pharmaceutical industry, where machine footprints are getting smaller, our design engineers have been developing products to fit those smaller footprints.

What ZSi-Foster Food and Beverage, Medical and Pharmaceutical Customers Are Saying…

  • "We love having direct access to your engineers."
  • "Your knowledge of flow and pressure drop requirements is exceptional."
  • "ZSi-Foster gets high marks for product availability and on-time shipping."


Straight-Thru FST

Did You Know?

ZSi-Foster was the first to market with the Straight-Thru FST for the food and beverage market. Innovation is key to our success. Our engineers developed a 1/8" FHK for the medical industry without changing the envelope size or lock. We achieved a 37% higher flow rate over the competitor's product. You get direct access to our engineers to develop products, run tests, and try various product iterations to see what works best for you.
