Regarding Fittings

Question

Dear Sir/Madam

Hello,

I own a variety of both soft/hard tubing fittings ( refer to my account ) and  INTERNALLY, some have a CHROME-looking finish, some are WHITE and some are BLACK.

Firstly this is not a complaint or any kind of warranty claim or issue!

I wanted to ask you the following questions please :

1. Is this all Nickel Plating? would you be kind enough to explain why some are different colours as I usually associate Nickel plating as being shiny like Chrome plating.

2. What happens if I have scratched & damaged this plating INTERNALLY so that the Brass Core material is exposed to Coolant fluid ? will this deteriorate the Brass that is exposed and tiny bits of Brass will be stripped and carried around in the coolant solution ?

3. i.e. if I have scratched and damaged this internal plating is the fitting unusable?

4. Also I cannot log into my account from my pc, are able to help?

Thank you for your technical support.

 
Kind regards,

Max Lord

Dear Max,

We are glad to answer your questions.
1. The black and white fittings both are metal electroplating. But the white one has one more nickel plated. 

2. If you scratch and damage the plating, the plating will be peeled off.
But even if the brass core material is exposed to coolant fluid, it would not have much affection in the loop. The brass won't be stripped and carried around in the coolant. But the plating needs to be filtered and cleaned. If not, it will block in the water block or radiator.

3. After you clean the plating, the fitting is still useable.

In normal, the plating is not easy to peel off when you use the distilled water or our coolant as the liquid. Please do not use the coolant which has alcohol compounds. It will affect the plating and O-ring.

If you have any questions, feel free to contact us.

Best regards!
