P5515 Hydraulic Comparison Test Pump current models are P5515-140M and P5515-140M-EP.
The latest version of the manual was published in 2010 when the model names were P5515 (nitrile seals and o-rings), P5515-V (Viton seals and o-rings) and P5515-EP (EP seals and o-rings).
The current model P5515-140M comes with Viton seals and o-rings and the P5515-140M-EP model comes with EP seals and o-rings. Models with nitrile (also called buna-n) seals are no longer available but the individual nitrile seals noted in the manual are still available (not as part of a kit).
A marked up copy of the manual is below (click on the link at the bottom of this article to view or download) for the current part numbers of o-rings and other parts that may have changed.
A video demonstration of use is at the end of this article.
It is often preferable to order an o-ring kit rather than individual o-rings. Here are the available o-ring kits:

The part numbers for the handles is not shown in the manual. This kit is suggested because the price is less than that of the individual parts for four handles.
