What thread is on the Launch Pad 725 lb fat sac? Cant seem to find anything that fits at Lowes. I know its not garden hose. HELP!!!

HELP!!!!! Someone has to know what the hell these fittings are!

First, what are you trying to do? Second, learn how to ask better questions.

? Sounds pretty simple to me. I am trying to connect a hose to the bag. I have gone to the hardware store and no such fitting was anywhere to be found that would match the male threaded portion of the bag. Thus I am trying to find out what the threads on a Launch Pad fat sac are... It does not have to be quick disconnect or anything fancy.

water bed drain and fill fitting kit.

I bought a pair of Launch Pads and returned them because I couldn't find any decent fittings. The Launch Pad guys didn't want to hear about plumbing there sacks in to a system. <BR> <BR>I bought Fly High sacks. They have a great selection of plumbing fittings.

If you want a more or less permanent connection try this. The OD of a 5/8" bilge hose will fit perfectly in the ID of a standard ballast fitting. Put a 1 1/2" hose clamp around the outside of your sac opening, gently tighten and your done. The OD of a 3/4" garden hose also works nicely. I have used these simple connections for my permeaent ballast for 4 seasons and have had 0 leaks or probs. The water bed fittings work, but I have found they come undone and can't imagaine they allow the same water flow. <BR> <BR>}

try a Male NPT threaded fitting from the irrigation section at Lowes or Home Depot. It has a finer thread (more thread per inch)than a male garden hose fitting. That is probably a 3/4" opening but measure first. Should be able to pick one up for about $1.50

Use a brabed fitting. Worked for me on my old fly high bags. <BR> <BR>1inch should do the trick <BR><img src="http://www.wakeworld.com/MB/Discus/messages/65921/500620.jpg" alt="Upload">

^^^thats what I used with a hose clamp use a little soap to get them to slide on.

you can also heat up the tube a little in warm water to expand it

Tried the waterbed fittings last night and I was only able to find one manufacturer. They are super lightweight and chincy. Can't say I would trust them with 700 lbs of water behind it. Thanks for the other ideas! I am sure one of them will work much better.

I used the same barbed fitting that Swatguy posted with a hose clamp around it. No leaks on my 1200# fly high couch.

Contact the guy at bulletlines.com if you want waterbed fittings. He hooked me up.

yeah, if bulletlines has what you need then talk to Ken.. I've even bought sacs from there and i was superpleased with his service level.
