Title: Hand pump lubrication
Post by: Taso1000 on May 18, 2016, 03:35:23 PM
Hi All,

I know this question has been asked a million times and the preferred lubricant is silicone.  But since silicone is not a great lubricant I'd like to use Krytox.  My question is: is oil or grease preferred?

I'd like to inspect, clean and re assemble my Xisico and Barska pumps.  I did see some brown liquid in the new Barska pump so I want to see what that was and halt it if it was corrosion or return it if there is serious damage.

I have a brand new tub of Ultimox.  If oil is better can I use Krytox GPL 106?  I will be ordering Krytox oil for other uses so I just want make sure the 106 is the recommended one.  Also Ultimox has corrosion inhibitors.  Do any of the oils have corrosion inhibitors?

I can get 106 and 105.  106 has a flash point of 500 degrees and 105 is 400 degrees.  107 has a flash point of 550 degrees but is much thicker and I can't find it to purchase.

What do you guys recommend?

Thank you in advance!

Who told you Silicone is not a great lubricant? Due to it's very low coefficient of friction it is an excellent lubricant for rubber.

If you must use something else I would say the oil due to the decreased viscosity.

Silicon may not make a Good metal on metal lubricant...  It's makes a fantastic seal lube....  Been using heavier silicon shock oil on my Benji pump for 4 years and have not rebuilt it yet...

You had my attention with Hand Pump lubrication, but this is over my head.

Sorry,  I am mistaken then. 

I "thought" silicone was preferred for assembly but not for repeated cycling.  Or am I retrieving what I've read jumbled up lol?

If you don't ask you'll ever know right?

Thank you,

Perhaps since its generally advised to not use any lubricant that could cause dieseling, the food grade divers silicone is a good, and available, non combusting lubricant.
just in the event the hose and everything got the lubricant.

I use the divers grease, the ring you se at the bottom of the pump tube, when it turns from grayish looking to a brown rusty color it is time to rebuild your pump, hopefully you rebuild before then.

Krytox GPL226 has corrosion inhibitors.  That's what I plan to relube my Barska with when it finally gets here.
