Supply Chain Updates

Last Updated - 1/12/2022


We continue to see and feel the effects of supply chain and logistics issues across the globe. With all this happening in an ever-changing environment, we wanted our customers to have a spot to update them on the latest price and lead time updates. As we hear and see these changes, we will publish them here. Check back often as this webpage will be updated weekly.

You can browse the latest updates by vendor by clicking on the links below. Please note that items back in stock will be labeled "Available" in the lead time column.

In some cases, we have substitutes available for the affected parts. If a part has an available substitute, click on the part number and click "view substitutes items."

Also, please note that in cases where vendors have issued surcharges or price adjustments we have those documented below. You will need an online account to view those web pages.

The table below was created internally by Stromquist. The data comes from our purchase orders and on average how long it has taken us to acquire the controls. Please note that some of the data was provided directly from Automation Components, INC. The table is intended to show you the expected lead time if your order was placed today. As you can see while not all of their sensor are experiencing long lead times but it seems that the humidity (RH) sensors have been impacted the hardest.

Sensus much like many of our vendors are beginning to experience some unexpected lead time issues. Stromquist & Sensus are doing everything in our power to minimize any effect we can. Regulators such as the 143-80-2 and 496 series are experiencing lead times of 2-4 months. Meanwhile we have no experienced longer lead times for the 243-8 or 243-12 series. We still have some of the High Pressure regulators available.

Although with the global market changing so quickly this may only be temporary. The table below is a current snap shot of expected lead times if you place an order today. Continue to check back for updates involving Sensus regulators. To view regulator substitutes, simply click on the part number and then click "view substitutes".
