    Lately the non-metallic seacocks became very popular in the area I am sailing (Greece).
    The most popular, by far, brand is a NewZealand company TruDesign.
    They claim they meet ISO 9093-2.
    I want to point out decisively that I have no interest in this company except for considering it's products for replacing old sea-cocks on my boat.
    I have no experience and knowledge on this type of products and I'll appricate the forums members opinions about it.
    thanks

    I prefer bronze. Bronze shows you when there is an issue with them before they break. Usually when they break it's a small piece. The Marelon, I've seen simply snap right off when they get old. Now it's rare, but I've seen it twice.

    I've had bad luck with composite handles on a few vendor cocks.
    Never been around a TruDesign unit but on the website, the handles look flimsy also.

    I raised heck to Forespar once, they pointed me to the tag that is attached to the cock and all their other install pubs. Operate cock monthly and use their grease.
    Rite,,,,,,
    I stay with bronze..
