PolyMax - 36/39 mm O-Ring for Wet End Seal Replacement - PPS-10361

PolyMax – 36/39 mm O-Ring for Wet End Seal Replacement

The PolyMax 36/39 mm O-ring is a small replacement part for use when you renew a wet end seal. It sits under the collar and gives a better seal, so you can leave out the silicone gasket. It is intended for use with the US Seal PS-1000 wet end seal, the PS-3865R and the 1092-AV.

Compatible wet end seals

This O-ring is listed for use with the following wet end seals:

• PS-1000
• PS-3865R
• 1092-AV

Before ordering, compare the reference on your current seal with the list above. If your seal is not one of these, this O-ring is not the right replacement part for your job.

Fitting and dimensions

The O-ring is placed under the collar of the wet end seal. Used this way, it takes the place of the silicone gasket, so you do not need to apply one when you replace the seal.

The dimensions are:

• Inside diameter: 36 mm
• Outside diameter: 39 mm
• Thickness: 1.5 mm

How to choose the right O-ring

Because this is a small, simple part, size is what matters. Check that the inside diameter of 36 mm, the outside diameter of 39 mm and the thickness of 1.5 mm match what your wet end seal setup needs.

If you are replacing the seal as well, choose the seal first and then confirm that it appears in the compatibility list above. This way the O-ring and the seal will work together.

Why add an O-ring when replacing the seal

A wet end seal replacement is the moment to pay attention to every sealing surface. This PolyMax O-ring is designed to provide a better seal at the collar, and it simplifies the job because the silicone gasket is no longer needed.

It is a low-cost detail, but it is worth having to hand when you open up the wet end and fit a new seal such as the PS-1000 or PS-3865R.
