Anodized BLACK. OD is 2" and allows for direct connection of a 2" scat tube.
These eyeball vents are FAR SUPERIOR in their construction to those seen elsewhere and are of much higher quality. These are the highest quality vents that money can buy. For example, the Black Vents are 100% anodized aluminum....and unlike the overpriced and low quality vents produced elsewhere, these black vents don't require a "Plastic Flange" because of metal to metal contact . That's a sign of poor quality construction with metal on metal contact. These high quality vents have a nylon/delrin bushing encapsulated between the eyeball and the flange to protect the aluminum! On top of that, the larger vents sold elsewhere require a THREE INCH mounting pattern....4 Bolts which is much larger than need be. With these vents you simply cut a hole, install the vent and tighten the plenum or retaining nut behind it and hook up the tubing!
The vents include everything needed for install...no need to try and cobble together your own plenum or flange for scat tubing. On the small vents you can just directly attach a 2" scat tube to the vent - and on the large vents they have 2" plenums. These will come with a "BAC" part number on them, but that's because they are normally for the cockpits of fighters....you can figure out what the initials are for!
Pricey, but they work great.
With the exception of price, these seem to be very well made. I did have to return the first ones I received because the plastic plenum wouldnâ€™t unscrew from one and wouldnâ€™t screw on on the other one. Aircraft Spruce promptly sent out replacements. Will give me a very clean looking install on my panel. I would buy again hopefully when they go on sale.
Nice vent, but does not include screw-on flange for back which connects venting flex hose to eyeball vent and rear cylinder is too large for flex venting to fit over. You need a screw-on flange with threads on end closest to flex hose end.
The vent has a 2" inlet and a 1-1/4" outlet.
These require a 2" hole.
No, these do not have PMA or TSO approval.
