Kraken de Mabini 67 Posted March 7, 2020 (edited) I got this flat glass port, maybe for an underwater housing, with a bunch of second-hand Subal housing stuff on Ebay from a reseller. The port is 90 mm outer diameter, has no markings of any sort. It has three O-rings, two by the bayonet mount, and one on the outer ring surface. Your kind help in identifying it will be greatly appreciated. Edited March 7, 2020 by Kraken de Mabini edit Share this post Link to post Share on other sites
bvanant 153 Posted March 8, 2020 That certainly is a Subal bayonet, but don't know if it is T3 or T4 Bill Share this post Link to post Share on other sites
Kraken de Mabini 67 Posted March 9, 2020 I have both the T3 and T4 Subal ports, and this unknown port is smaller than the T3, the bayonet lugs are also smaller and with rounded corners, so it is not Subal. Good try, but port identity remains unknown. Share this post Link to post Share on other sites
