stahlbus Oil Drain Valve 1/2 inches-20UNFx12mm, steel (set)

Product 11 / 13

1/2 Inch-20UNF Set

A conventional oil change is always associated with spills and dirty hands. Therefore, this system has been developed with which you can perform an oil change completely safe and clean.

The stahlbus®-oil drain valve will easily replace the existing drain screw. When changing the oil, you unscrew the cap and put on the hose connector via quick release. Only when this is locked, the valve opens and the oil can be drained into the provided container.

The advantages at a glance:
•   Easy handling due to quick release
•   Drain valve can not be lost
•   No risk of burns from hot oil
•   Seal change is not necessary
•   Sump thread is spared
•   Double outlet protection (protective cap and valve)
•   Connection to suction possible
•   Optimal application for discharge sampling or trapping
•   Protective cover against loss through O-ring
•   Change oil without tools

Thus, the oil change makes fun!

Assistance for determining the thread size

In order to find the Stahlbus Bleeder Valve that fits your purposes, you first have to measure the thread of the currently installed bleeder nipple. You may either use a measuring gauge, or you may download the template prepared for this purpose.

How to measure with the measuring gauge

You determine the thread diameter by measuring the external dimensions of the thread with the slide gauge.
To determine the thread pitch, you measure the length of four thread turns with the tips of the slide gauge. Always measure the distance from thread crest to thread crest.

If the value measured is 4 mm, the thread pitch is 1.0; if the value measured is 5 mm, the thread pitch amounts to 1.25.

How to measure with the template

Take the bleeder nipple to be replaced by a Stahlbus Bleeder Valve. Compare the thread successively to the different printed pictures of threads until you have found exactly that thread which is precisely covered by the valve. Please make sure the template is even and does not wrap itself around the valve.

For valves with a diameter of M10 you have to additionally determine the thread pitch. To do so, please cut out the left corner below of the template. Then hold the thread of the valve successively above both sides of the cut-out template for the thread pitch. You have determined the correct pitch if the serrated edges of the thread template exactly match the thread turns.
