Due to icy roads our Portland location will have limited staff today. Please call ahead and leave a message if no one answers and we will get back to you ASAP. Stay safe out there.

A note to our customers. This year has been very challenging. Thank you for your patience and commitment to the products and services we provide you. During the Covid-19 pandemic we have been hit with a number of set backs that have slowed the processing of most orders. Despite these circumstances we are working hard to come up with creative ideas to quicken our response and get your orders to you as soon as we can.

Braintree Supply Store (E-Mail Braintree):
Please place your orders at least one day ahead of time. It is easiest if you email a list of the items you are looking for to braintree@portlandpottery.com. We will call you as soon as your order is pulled and ready for pick up. Our Braintree store still remains closed to foot traffic, but you can still place orders for curbside pick up. We will not be able to fire kilns at our Braintree location until further notice. We apologize for any inconvenience.

Portland Supply Store (E-Mail Portland):
Our Portland store is open for browsing. We are happy to have you back in the store again! Two customers at a time please. Curbside is also available in Portland. It is recommended to place the order ahead of time whenever possible.

Identify Your KilnSitter Model

There are four main KilnSitter Models. These Model numbers are printed on the face of the KilnSitter unit and they are: Model K, Model P, Model LT-3, and Model LT-3K. Skutt Kilns only use Model K and Model LT3-K units. Older kilns, and some custom Kilns did not come with printed face plates. For these Models it is best to call Skutt to make sure you identify the correct part.

Measure Your Tube Assembly and Sensing Rod


Most parts are interchangeable from model to model however the style and length of the Tube Assemblies and Sensing Rods used in KilnSitters can vary depending on the brand of kiln and kiln model. The two styles are pictured below. The “P” Style was used in Model P and Model LT-3 units whereas the “K” style were used in Model K and Model LT-3K units.

Once you know the style you will need to measure the tube assembly as shown in the photos. When you go to purchase your part simply choose the tube assembly that is the right size out of your parts list.
