sealer

A case sealer or box sealer is a piece of equipment used for closing or sealing corrugated boxes. It is most commonly used for regular slotted containers (RSC) and can involve adhesive (cold water-borne or hot melt adhesive), box sealing tape, or Gummed (water activated) tape.
By contrast, a case erector is equipment for setting-up flat (knocked-down) corrugated boxes and applying a closure to the bottom flaps.

    Leaking central heating - should I use an internal leak sealer?

    I have an 18 month old central heating system with a combi boiler and pushfit pipework. Everything works OK but the system loses pressure after about 3 months. I can't find any obvious leaks or weeping joints. Would a leak sealer like fernox f4 be a good solution? Thanks

    Leak sealer is PVA?

    Just put some leak sealer in a system and I'm pretty sure it was just watered down PVA. Maybe it was because it was cheap off the bay? Didn't really fancy spending brand prices if they're all the same. If they're not then what works best?
