Check out this simple, easy-to-follow guide on how to install stainless steel fittings.
00:10 Importance of using anti-seize
00:35 Install permeate fittings
00:49 Apply anti-seize
01:05 Secure the thread fitting
01:18 Repeat process for thread fasteners
We like to recommend the use of anti-seize whenever you're installing a stainless steel fitting or fastener into one of our cells. The reason for this is stainless steel has a tendency to gall, meaning the fittings and the threads will seize or get stuck when you're installing them or removing them. Once again, the best way to avoid that is the use of some anti-seize. Here I like to use some loctite silver grade anti-seize. There's others on the market, just make sure it's compatible with stainless steel.
All right, so when I'm going to install one of our permeate fittings, I'll start with four to five wraps of our PTFE tape on the threads, should look about like this.
Then, of course, we'll move on to our anti-seize comes on a brush, and we're just going to apply about that much to one side of our thread, and then thread that in by hand.
We get that hand tight. Then, using a 9/16 in wrench, let's get it to about 15 to 20 pounds of force. To make sure that's secure.
Let's make sure we do the same with any of our straight thread fasteners. These are stainless steel as well, so we're going to make sure we apply a generous amount of antiseize to one side of the threads, and then go ahead and thread those in.

Sterlitech HP4750 Stirred Cell
The Sterlitech HP4750 stirred cell is a high-pressure stirred cell that is both chemically resistant and features a low hold-up volume (1 ml). This particular brand of stirred cell is able to perform a wide variety of membrane separations.
HP4750 Stirred Cell Product Benefits:
- Max operating pressure is 1000 psi
- Removable PTFE stir bar
- 316 stainless steel
Applications
Safe Operation: Volatile solutions can be processed safely because the Sterlitech™ HP4750 operates on standard sources of compressed air or inert gases (nitrogen, argon, etc.). This provides the user with a variable, safe and consistent supply of pressure to effect membrane separations.
High-Pressure Operation: Solutions with high levels of dissolved solids and high osmotic pressure can be separated with the Sterlitech™ HP4750. The cell is designed for safe operation to 1000 psig (69 bar).
Removable Stir Bar: Concentration polarization at the membrane surface is minimized by a PTFE-coated magnetic stir bar mechanism. The stir bar can be driven by any standard stirring plate.
Accepts Standard Membrane Discs: Sterlitech™ HP4750 Stirred Cell accommodates any 47 to 50 mm diameter membrane disc.
Chemically Resistant Materials of Construction: 316L stainless steel construction makes the Sterlitech™ HP4750 resistant to most chemical degradation. Buna-N gaskets and O-rings are provided as standard with other optional materials available to meet operating requirements.
Unique Design: The cell top can easily be removed to fill the vessel with up to 300 mL of solution. The cell bottom is removable for quick membrane change-out. The top and bottom are secured to the vessel with mechanical couplings. This unique design enables low hold-up volume, down to as low as 1 mL, so valuable solutions are not wasted.
