Tectite slip fitting

[Bogart]

Trying to use a 28mm tectite slip coupling. Mangaged to get it over the pipe push it down, with some effort, but am damned if I can get it to come back. Am using the demounting tool and the plastic collar is all the way in but am damned if I can get it to come back on itself.

IIRC, you can use clean water as a lubricant (but nothing else).

Edit: BTW, don't under any circumstances lose concentration and stick a finger into these fittings while trying to figure out what's wrong. The nick-name "shark's teeth" is not a joke.

Agreed I do not want to spend the rest of my life in the airing cupboard. Oh and by the way think it needs more than clean water.

I'm fairly sure that the manufacturer's installation instructions say 'clean water' and don't use anything else. At least, that's what they said a few years ago because I remember reading them when toying with the idea of using some soap.

I use food grade silicone lubricant when I have to lube up one of these.

Am currently in discussion with Pegler. Their blurb mentions the O ring is already lubricated.

Yes, the new ones I have here have a smear of silicone inside them and it looks like they put the lube in the o-ring seat/groove first then put the o-ring on top of that so some lube squeezes out either side of the seal.

Finally got a reply from Peglar after chasing them 10 days later Answer yes 28mm is harder to use than smaller sizes, brilliant answer.
