12 Years Factory wholesale Expanded PTFE Tape for luzern Manufacturer

Expanded PTFE sealant tape possesses all the properties of PTFE, resistant to all the corrosive media.

Soft, twistable and bendable at will. Even if gravely rusted and worn out sealing face, as long as it is used, the equipment units may continue their service and the sealing can keep its best performance.

Excellent anti-wriggle variation ability and cold current resistance. Even in case of cross change of temperature and pressure, good sealing can be assured.

l Easy use and replacement

l Wide service scope.

Technical Data Sheet

Regular Size

Application Area

It can be widely used in diverse pipelines to seal flanges, enameled products, glass, rubber products, plastics, non-rusting graphite lining tower, heat exchanger, pressure container as linings and to seal their flanges, to seal the fillers of diverse pumps and valves and to seal much heavy-calibre flanges which are not so precise, have larger unflat area and irregular shapes and require not too large tighting force.

Demo (plasma) Fusor

Pyrex glass laboratory drain pipe “vee” mitered elbow fitting used as my vacuum chamber.
One opening is 3″ inside diameter and the other is 2″ inside diameter.
I bought it on eBay for $14.99 plus $11.99 shipping for a total of $26.98

Variac brand variable transformer for varying the ac input to the power supply.
This is the 5 amp 500VA version. SC-5M. My power source is 5000v at 18 milliamps, so 5000 x 0.018mA = 89 watts which is basically 89VA. The 5 amp Variac is obviously capable of handling the 18mA. On the faceplate of the Variac it states a maximum of 500VA which again is way more than my 89VA power supply needs. Amazon $81.24

Cenco 5000v AC output spectrum tube power supply. Cenco model #87208
Came with a 3 prong cord. No ground fault interrupter to cause problems. I tested it by making a Jacob’s Ladder with it and it didn’t explode. It came with 2 unattached wires that a little research showed were for an on/off foot switch. I just connected these wires to each other and tucked them inside the unit.
Antique Shop $4.

Silicone (clear) covered high voltage wiring rated at around 6 times my voltage and amps.
This wire is limp like a wet noodle, some people call it “noodle wire”. This wire is capable of handling 44,000 Volts AC and 31,000 Volts DC. Way more than my 5000 Volts. It can also handle up to 11 Amps. Again, way more than my 0.018 Amps. Always check Volts & Amps! I bought 10 feet. McMaster-Carr 962T15 $20.80

Silicone Rubber Stopper. 2 13/64″ for the 2″ hole. Purple.
NASA has a free off gassing website showing which materials lose more weight after being subjected to a vacuum. Nitrile loses over 1% of its weight in a vacuum: meaning 1% of it flies out into the vacuum chamber and ruins your level of vacuum. Silicone only outgasses 0.31%, so it’s way better! In a deep vacuum even the oils from a fingerprint outgas and mess with the vacuum levels. NASA outgas list:

McMaster-Carr 922K79 $5.34

Silicone Rubber Stopper. 3 35/64″ for the 3″ hole. Red.
McMaster-Carr 9277K71 $16.81

Stainless steel wire 302 steel. 35 feet (1/4lb). Bend and Stay. (0.051″ diameter).
Used to make the inner and outer grids. This didn’t work as well as some thin scrap copper I found, but didn’t melt.
McMaster-Carr 8860K16 $6.51

Alumina Aluminum oxide ceramic rods with two 0.063″ inner diameter holes.
It was 2 feet long and impossible to cut with a variety of cutting wheels. I eventually just clamped it in a vise and tapped it with a hammer to break pieces off.
Amazon $11.20

Laboratory stand for assembly, but not actual use. Cast iron base.
Amazon $14.67

Eisco 90mm Lab Clamp.
Super nice clamp that was the only one I found that could hold my huge vacuum chamber.
Amazon $14.20

A 3 CFM 22.5 micron Philadelphia brand vacuum pump.
It sprays out a fine smokey mist, but that mist doesn’t seem oily and dissipates. A while later the pump starts leaking oil. This is all considered normal. The pump wasn’t too loud either.
It came with slightly more than enough vacuum oil needed.
Harbor Freight with a 20% off coupon and shipping for $143.08

Valve manifold fitting consisting of two ball valves.
One valve seals the vacuum chamber, the other allows the vacuum pump be routed to open air seconds after it is shut off. Without this valve vacuum pumps would spit oil and condensation into the vacuum vessel. This happened once to me when I forget to let the pump up to air.

Pipe Thread Compound with Teflon
Used by plumbers (and me) instead of Teflon pipe tape. Never use tape on vacuum fittings. This is a liquid paste made by PlumbShop #PS2434.
Local hardware store $1.98

Safety full face mask (probably the most important item of all).
