Hello!

We appreciate you reaching out to us. It looks like you may have something like our S351-13 or S390-13 with the 1220 option depending on the depth of the bottom fitting. You'll need to measure as shown in the image below to determine which Series you have. 

Please note, the top and bottom fittings for both of these Series are wingless. Your tape measure is obscuring part of the top fitting so it's hard to say if this is the case for yours.

Thanks for the quick response. I measure and it looks like it's apart of the 90 series and you mentioned. Mine does have wings on the top. I've attached pictures. Here's the one I found based on your suggestion.
