T.F. Purifiner Inc. TF12P bypass oil filter, new in box with mounting and connecting hardware.

This unit has a built-in 12v heating element designed to evaporate water and volatiles from engine lubricating oil; this is designed to prevent the filter element being clogged by moisture in the oil, which is not uncommon in marine engines or infrequently run gensets etc.

 Element is to be connected to vehicle wiring for power obviously.

Apparently later versions of this filter do have the vented heating element due to EPA regulations, making them much less effective IMHO.

The filter element is a sealed tin containing cotton fibre.  Manufacturer states filter change interval as 60,000 miles.

Buyer assumes all liability for conformity to US or international law regarding importation and use.

Why run your engine on increasingly dirty oil, then pay to replace it and repeat the process?  Keep the oil clean all the time and neither it nor your engine will wear out!

I have four of these units all NIB and another box with four new filter elements for the TF12 and various new spare hardware.  Whoever buys all four will get the spare filters and hardware free, and with combined shipping (at buyer's cost), within the per package size and weight limits of the Post Office.

If you want to ship UPS or FEDEX on your account (to allow larger parcels), that can probably be arranged.
