Hi Brains Trust!

 

Cannot find on google. Just bought replacement glass for my Nauticam Macro Port 87 - any tips on removing and replacing? Not as easy as I thought - trouble removing existing o-ring to get the old glass out?

 

Cheers

If we get an answer to this, I'll pin it. It'd be really useful.

 

I saw it done some years ago when I worked in Lembeh. Shen, one of the techies from Reef Photo, replaced the glass on one of my Subal ports.

 

It took him about 10 minutes to get the old glass out using a modified cut-down dental pick plus an approx 4" lever he'd made out of thick acrylic - or polycarbonate. It looked like a push bike tyre lever. It was one of those pick-pull-lever-curse-pick-lever-mutter-lever-bingo manoeuvres.  Popping the new glass in took seconds. It was very impressive!

 

I scrounged the lever and pick off him in exchange for free diving..... I've never done it myself though. Probably just as well.

Hi,

 

did`nt do it on a Nauticam Macroport. But I replaced glass on a Hugy Macroport and removed one on my Seacamport. I pushed out the glass from behind with something suitable. (I used a hammerhandle).It take some strenght and you must be careful that the you push the glas out parallel to the port housing. Getting old stuff out is usually harder than mount the new one. Use new O-Ring some grease and mount the new one is usually easier to handle with less force. Again be careful mount the glas parallel to port housing.

There was a post describing this on the old forum as I recall but the search function is not being co-operative.  As I recall the process is to push out the old glass, possibly gouging out the old o-ring. 

 

Note which side is up!

 

Place new glass in place, grease the new o-ring place in groove and start to work around the port pushing in the o-ring till it is seated, using a blunt soft tool.  This is what I recall, but do you think I can find the post ?!?!

 

Did you try asking the supplier for an installation guide?

Hi,

 

looked at my Nauticam port. Same installation of glass as Seacam & Hugy. Install big phase on the glass outside/waterside. I`m no native speaker and my english is not the best to explain the procedure. Might be it helps.

This is my recollection of how mine was done. I think having a new o-ring available is important. The old one may well be damaged during the extraction process - especially if you use a dental pick!

I finally came across this post:

which outlines the process.

Thank you all… replacement came with new oring, good as i cannot see how i could remove without damaging it. Appreciate the responses I will let you know how it goes after the weekend. Cheers

It would be good if someone could take pics of you in action removing that glass, John. The strained expression, the frustration, the torn knuckles, the beads of sweat...... capturing that FFS look?

The old o-ring is out! The glass is out - now to get the sucker back in !

Well done, John! I think the tough part is done.

Hi Tim -- Two years later I have finished the job! Been surviving with a macro 60 port and extension but for whatever reason decided today I will change it! Already had the glass out - last time I tried getting the -o-ring in was frustrating and I gave up. But perseverance seems to have worked. So glass bevelled edge facing out from the port - lots of lube on the o-ring groove, outside edge of glass and the o-ring - worked o-ring into the groove with the curved edge of backcsatter snoot insert. All easy until the last little loop is left in the o-ring - tried several times - but good old lube did the trick - added more lubricant to that last little bit and it popped in, hopeful;l;y without me damaging the o-ring! Housing set with vacuum pulled overnight and will see!

Wow, what an epic. Contact Christopher Nolan and sell the rights, Homer!

Congrats, John!

Wish i’d have seen this post before I ordered a new macro port from Nauticam to replace one with blotches on the glass.

They sell new port glass but its not exactly cheap. Surprise!

Hi.

A few years ago, I replaced the port glass on my Hugyfot macro port. It’s absolutely no problem if you have a little bit of technical know-how. Though removing the existing glass was a bit tough. If I recall correctly, the cost for the glass and O-ring was around €20-25. I think it’s a bit more expensive these days. Plus of course Nauticam bonus+++++.😁😁😁

I posted about my Curved Macro port project, and in the course of that I destructively removed the o-ring from a Zen port, and installed new o-rings in prototype ports about 6 times. I used 50 cent buna rubber o-rings from McMaster Carr and they work perfectly.

I eventually got pretty quick with the installation using a dryglove plastic prybar and plastic credit card for pressing in the new o-rings.

FWIW, I needed glass on a macro port replaced. My Nauticam dealer service guy did not charge for the labor, just price of glass and shipping. Said it would take about 10 minutes. Might be worth checking with your usual source of Nauticam (or whatever brand you have) to see what they would charge. I think shipping cost on a port was well worth avoiding the stress of doing it myself.
