• Dripless Shaft Seals - Heads up
  • I had a Lasdrop put in 2 years ago
  • I HATE them
  • On mine
    • Without knowing the brand of the seal in question...
      • Sorry... Still HATE em.
        • Hate is a bit strong
          • With so many great upgrades available, replacing such a simple elegant solution as a bronze stuffing box for a dripless,
            • I had my shaft out last Fall and went back to a traditional stuffing box...
      • We ahve been very pleased with PSS
        • I odn't understand how the collar could slide
          • Agreed that a well tightened screw is
          • It happens rather easily....
            • Interesting point on the set screws
    • A shaft zinc is not a good set collar.
      • Hagar is absolutely correct. My surveyor
        • Interesting. Gene warned me about the shaft sliding out, ...
      • Another Millwright's trick with set-screws.
      • It might not be ideal
    • The only downside of the hose clamp is
      • Only 2 left in stock (more on the way).
        • One Ruland shaft collar arrives, to solve the problem I didn't know I had!
          • We won't have any puns on keeping your shaft dry, and the like?
            • That would be the RutLand model.
    • To stop shaft slipping
  • Thanks for the tip Jon
  • How does one inspect these dripless systems?
    • Lasdrop said to just look at it once in a while. PYI???
    • I burp mine about once a month
      • I just look at mine once in a while.
  • A friend just finished PR to Maine, and their 18 month old shaft seal failed.
    • I just don't know what I would do.
      • That would probably do it. You could loss a stuffing box too.
    • Failure, failure, failure
      • No failures I know of
    • When Camper & Nicholsons fitted dripless seals
  • US Navy uses them on submarines.
