Frequently Asked Questions

Why doesn’t pricing show for a part online?
Pricing isn’t shown because you might not be logged in, and it only shows for make-to-stock parts. Additionally, some special-order items may not have online pricing readily available.

Why does it say call for availability on the online shopping cart?
A possible fix for regionally available items is to say that they are typically available in 5 business days. Some special items will require a quote from our customer service team to determine current lead times.

Why is my lead time different now than when quoted?
We provide live lead times at the time of quotation. Due to this, the lead time may change when your order is placed depending on the time between when your quote was provided and when an order is placed.

Is Swagelok the same as push to connect?
No, push-to-connect fittings, as the name suggests, complete the connection by pushing the tubing into the connection point. They’re typically designed for lower-pressure poly tube-style connections. Swagelok fittings are designed to accommodate a much larger variety of applications at various levels of pressure. Swagelok mechanical grip fittings complete their connections through the swaging process.

Can I use Swagelok ferrules with another brand of fitting (and vice versa)?
No, Swagelok does not promote using Swagelok ferrules with any other fitting manufacturers.

As a result, every fitting manufacturer can design and build fitting components to their own design standards. Due to this, Swagelok cannot guarantee that our fitting components will provide a safe, leak-free connection when utilized with another manufacturer. Below is video about the risks of intermixing or interchanging tube fittings.
