Vacuum Fittings - Female NPT

NW / QF / KF / ISO Sizes for 10 / 16 / 25 / 40 / 50

These are your basic flange adapters for mating to standard pipe thread holes. FNPT = female national pipe thread. Again most any material you desire although our standard fittings come in both aluminum and 304 stainless steel. We can make these in a variety of other materials including plastics and brass. We make specials no problem. I say no problem but specials should have some quantity behind them or they get pricey. For Thermocouple gauge tubes use the 1/8" FNPT adapters.

These items are packaged loose in baggies. Nothing fancy, but the price is right. Machined out of solid bar stock.

We recommend our PST Sealant for assuring a good seal where the thread goes in.

I haven't had the time to back fill these prices so if you want to purchase and need the prices we have them all laid out for you in 2 different formats.

** For thermocouple gauge tube adoption into systems. 0-30" gauges too.
