Sur-Prep® 123 is an environmentally sensible solvent that is designed to replace HFC-225 in a variety of applications. It's solvency and physical properties makes Sur-Prep® 123 ideal for precision cleaning, drying of high sensitivity parts, and cleaning of oxygen systems.
Sur-Prep® 123 is an excellent solvent replacement for a variety of cleaning processes such as instruments, APU kits, bearings, and oxygen system equipment. We always recommend pretesting Sur-Prep® 123 on sensitive plastics as Sur-Prep® 123 will craze acrylics, but is safe on polycarbonates, PVC, PET, HDPE, ABS, and others. With regards to elastomers, it will affect EPDM, NBR, and Buna, but is safe on Viton, Neoprene, Butyl-rubber, and others. Bulk containers come with a CGA 165 valve that can be adapted down to whatever size will interface with the oxygen line being serviced, including flare and Swagelok fittings. Aerosols can be used for cleaning the oxygen system fittings.

Best priced around great and speedy service!
Also is the better of the 2 options since it is rated at 5,000 psi, not that I go to that high of pressure but I like the safety and security knowing that my chances of it blowing up in my face are a whole lot better and I can also purchase replacement seals for them at the same shop!!!
I bought the DC PTT because I know and trust the DC quality/durability to hold up to using every day. And so far it’s the best PTT I’ve used. I have a couple other no-name PTTs and the cable sheathing is crumbling and falling off. The DC PTT has worked even in sub zero cabin temp conditions when I didn’t have a functioning heater. I bought two to have a spare but the first one has been working great for 300hrs so far.
