75 kg gas ram

Yogi, you need to keep the chrome rod clean and avoid contamination. If your rifle is fitted with the chrome rod in the piston, you shall store your rifle barrel down, butt up.( I suggest by hanging ). Please read the manufacturer recommendation about the gas strut orientation and storage again. There are lubricant fluid or oil in the tube of the gas strut specially for the seal.
 The hatsan vortex struts have some lubricants too but very , very, very little. During the cold season,  this lubricant may harden and may not flow to the seal. And all the hatsan vortex rifles are fitted with the chrome rod in the piston, and owner usually store their rifle butt down , barrel up in the cupboard or safe. Or on display rack that is horizontal.  There is very little lubricants in the vortex strut, I know because I  cut and examine the original vortex strut. I can smell it but nothing flow out from the tube of the strut.
There are numerous complaints of the ''honking" sound from their newly purchased Hatsan vortex rifle... l believe the seal in the vortex strut has no contact with the lubricants,  causing the chrome rod and the dry seal rubbing thus making the sound and echo out from the cylinder.
Please read the manufacturer recommendations, that I post before,  carefully.  And analysis the effective orientation for your rifle.

There is also a video by Mr. Mike Ell. on YouTube, he cuts the vortex strut and show everyone what is inside the strut , the rod and the small plastic piston in them. Then you will realise and understand that the lubricant can remain at the bottom of the tube (housing) if it is oriented with the chrome rod up.

Here's that video:
He's got quite of a lot of interesting air rife videos.

This is a piston M90-100 red force 70kg equal to 140 atmospheres,
I have just arrived from the factory and as you can see it has a little bit of vaseline fat on the base of the chrome barrel.
Vasellina because natural fat does not ruin the high seal gaskets.

I use these normally as shock absorbers on plates of industrial scales.

Ciao


Ps; I just did a little research on google and apparently this product we use it so much only here in Italy

Francesco,  the grasso vaselina contents are paraffin , mineral oil and some others. Paraffin  is similar to petroleum jelly. It maybe suitable for keeping the seal in good shape that you have experience them with the scale that you are working daily.  Thanks for sharing your find.
But is the paraffin in the vaselina be suitable on the piston rod that install in the air rifles   I don't  know .
Do they emit vapor or fumes that can mixed with the air within the cylinder and travel into the the compression chamber???
 I don't know too.

There is a video on youtube by Guns of Liberty. The title is " How to make your air rifle into a deadly weapon - Taylor's homestead visit"

I have found another manufacturer's recommendation about maintenance of gas strut.

they come with the grease on the axle from the factory, perhaps because they are built for purposes other than the airgun

Is there anybody,  who install their Hatsan rifle with the Crosman NP 2 gas ram?
Hopefully,  they can post their comments or experiences about the NP 2 's durability and availability.
There are lots of members here that are interested in them, will appreciate all comments and suggestions to share.
There is a video by "firearmsguide" on YouTube about the NP 2.
The title is

I have installed the less powerful NPAW nitro piston into my H85 sniper before.  The NPAW nitro piston has almost the same dimensions as the one in NP2. I am pretty sure it can be done.
