Once again, remember that measurements may vary from specs by about 1/8" due to expansion or shrinkage. Note: If your filter has a handle top and/or fitting on the other end,do NOT include these in your length measurement. Hole Diameter Your filter may have a hole in one end (with a handle top or closed top), or it may have a hole in both ends.  Measure diameter(s).  This is the actual hole diameter, excluding taper, if any. (Closed-top filters often have small pin-holes to allow trapped air to escape when installed.  Ignore pin-holes for measurement purposes).  See notes on Removable Fittings below. If your filter has a slotted-hole, measure the shortest way, not including the slot. The 2 most common slotted hole sizes are: 1 7/8" (1.9") and 2 3/8". Threaded Filter Types For filters with male threaded fittings, you will first need to determine the type of thread. There are only two types used:  Regular and SAE, so it's easy. Regular threads are fine, tightly spaced, with relatively sharp edges. The SAE type is a very coarse, widely spaced, flat-edge thread. See notes on Removable Fittings below. Thread Sizes After identifying thread type, you will need to determine the thread size for filters with regular (fine) threads.  Regular threaded filters are listed in 2 nominal sizes: either 1 1/2" or 2" MPT (male pipe thread).  1 1/2" MPT actually measures 1 3/4" outside diameter (OD); 2" MPT measures 2 1/4" OD. Since there are only a few SAE threaded filter types, it is only necessary to verify the SAE threaded filter's other dimensions and style to confirm that you have a perfect match. Male Slip Fittings Hot tub filters with smooth (non-threaded) male slip fittings come in only 2  nominal slip fitting sizes: 1-3/4" which is the actual outside diameter (OD), and 2" which measures approx. 2 1/4 to 2 3/8" OD, depending upon the filter. Removable Threaded Adapters If replacing Pleatco brand threaded cartridges, note that these have removable male pipe thread fittings which slip-fit into a 1 7/8" round or slotted hole in the filter bottom.  You may need to reach down into the canister to unscrew the male pipe fitting from your spa's filter housing if it did not come out with the old filter (many spa owners are not even aware that the fitting is still in there).   Most threaded Clarathon filters have the thread fitting molded into the end cap as a single piece. It stays with the filter cartridge for ease of removal & replacement.   Reading a Tape Measure Tape measures have lines & inch marks across the face. The scale between inch marks is divided into 1/16" increments. There are four different sizes of lines between the inch marks. The longest line represents 1/2", the second longest 1/4", then 1/8" and finally 1/16". The value of any line on the scale can be described in sixteenths of an inch, but it is customary to give the value of the line with its lowest common denominator, i.e. 6/16 is given as 3/8.     Place a Bid!
