Centering Rings

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

These are your basic flange fittings for closing over or blanking off a standard port of the sizes listed.  We will make these in whatever 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.

Elastomers for the o-rings usually used on these items are Buna-n, silicone or perfluoro (Viton).  Stainless and perfluoro is the choice for chemical contamination or aggressive environments.

These items are packaged loose in baggies.  Nothing fancy, but the price is right.

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.
