Hose Conversion Adaptors
929560
First of all I am trying to rate two hose adapters and your Amazon site is calling it a toy and asking me how I rate it. It is not a toy and it will not let me skip that part. I would rather my stars on rating the so called toy remain empty since it is not a toy and I am not happy with the purchase.  So........ We ordered these two hose adapters which came from the  Kern River Corporation in Lake Isabelle, CA. They were not the correct size. We paid $21.48 for 2 items we can not use. We have called the company several times only to get an answering machine and not call backs. We have emailed them 2 times and got no response. We would like to return the item but they will not respond to our questions on how to do this. I think this is a very poor way to treat a customer. I am glad it is only $21.48 that I have lost. I would not recommend anyone buying anything from them.

Pump is fine, but the plastic adapter extension to attach the hose is the wrong diameter.  I finally did a work around, but why couldn't they supply a plastic extension that fits?  Pretty sloppy! Should have sent the whole thing back!

This works as it should after a slight modification. As shipped, most hose or fittings will fit properly. I used a heatgun and a simple mold to chang the port to be 2-1/2 O.D. so that standard flexible hose will slide right over the port. Something Powertec should have done. That way, no additional adapters would be needed and cause it to become bulky.
To make the modification, use a heatgun to heat the port until to becomes flexible. Then press it down into the homemade mold that has a 2-1/2 hole. Allow it to cool before removing from the mold.
See photos for modification end results and homemade mold that was made to shrink the port.

used on an LS conversion.  Be aware it may be wise to use 3/8 diameter hose to 5/16 fitting, the 5/16 line has a very small hole to fit the hose end of this connector.

Not a good adapter set.  I had to buy another piece to fit on to the 2 1/2" accessories.  If you have a Rigid wet/dry vac, buy Rigid.  It is less expensive and fits without an extra piece.

Works very well for adapting various air brush makes to a 3/8" air hose. I used the one for my Badger air brush.

The TCF73 hose adapter worked very well in my application repairing small diameter hoses.

Great Product.  This hose has an adapter that fits perfect on the original hose of my Ridgid vacuum. The various hose attachments allow for vacuuming all part of my cars and performs as I hoped it would. This was a great investment.

Does not fit, diameter too small for pipe fittings. I have the standard 1&1/2" hoses. Will not work unless it  buy all new small adapters

I have presta valves. The damned adapter is junk and has disintegrated making the pump useless.

Worked great on replacing my lines on my 2015 Keystone Outback.  I initially thought I got the wrong size but then realized that the old line had the 1/4" adapter that I needed to fit into the regulator.  These work great!

Great product. Adaptor was needed for me to fit the two hoses together, super easy to find in the hardware store and the employee knew what I was talking about right away so apparently it is a common fix. Can't complain, super easy to install (with the right tools on hand).

This is an innovative quick connect hose fitting system.  So far they are working very well.  I am using them to swap out different gardening attachments -- watering wand, watering nozzle and feeder system.

Okay the vacuum I use has a 1 7/8" hose fitting,  however this hose is a 1 1/4" fitting which forced me to adapt my hose connector to the Cen-Tec Systems hose.  Once I sealed the connector with a product called Goop the hose worked perfectly with all of the attachments.

I used this to adapt a 1.5" dust port on an oscillating sander to a 2.5" hose attachment.  The small end with a piece of tape on the port fit perfectly.  The hose attachment fit over the other end once the clamps was pulled off.  See my review on the Grizzly sander.

Adapters fit the valve good. just no bottom to the knobs so hard to push down on valve. looks are good and hopefully can fix the push issue.

DO NOT BUY IT. IT IS N0T FOR MODEL 91250. IF YOU THINK USE THIS THINGS CONNECT TO HOSE TO PUMP FORGET IT. EVEN THEY ARE NOT ADAPTOR.
