not your ordinary customer

I put these caps on the bottom of wands that I make for ceremonial purposes for wiccan, druid, pagan, and fun...the caps give my wands a look that is totally mine.. I also use 1/2" and 3/4" for my bigger wands...

Most Liked Negative Review

Cap was so, so

The product was shipped quickly, but as I was using this for a finished item it was pretty marred and scratched. I would recommend for a normal use, but not for a finished product. I was able to polish it after considerable time getting the scratches and nicks out. The rating is only fair for the use I had, not that there was anything wrong for normal use.

Accurately Dimensioned & Packaged For Safe Mailing

These caps fit properly! Copper caps are not the most complex fitting available, but I've purchased many from wholesalers and retailers that crazy-loose. Sometimes the fit is so bad that Bridgit or brazing is required. SupplyHouse must have a good supplier for copper as their fittings always work out. They ship well packaged and FAST!

Q: I have some 1/4" OD copper tubing I would like to use for an art project; I purchased some 1/4" copper caps from the hardware store but they were much too large. Does the 1/4" measurement listed for these caps mean that they are 1/4" diameter on the inside so they would fit a piece of 1/4" OD pipe?

No those caps are made to fit 1/4" ID tubing so they will be too large.

Q: What is the ID of a 5/8" copper cap?

A 5/8 copper cap should have an ID of 3/4 inch to fit on a 5/8 OD pipe.

Was this review helpful to you?

When they say 5/8” that is the “nominal size” and it is 3/4” OD and 0.668” ID. You use this 5/8” cap on a 5/8” copper pipe (i.e pipe that is 3/4” OD and 0.668” ID).

Q: What is the inner diameter of the 1 1/4 end cap? I have a pipe that is actually 1 1/4 inches in outer diameter. I had bought a 1 1/4 end cap (from a local hardware store) was too large, so I want to make sure I get the right end cap this time. Would a 1 inch end cap be better?

INER DIAMETER OF 1 1/4 END CAP IS APP. 1 9/16 ALL FITTINGS ARE SIZED ACCORDING TO INTERNAL DIAMETER OF PIPE , SO IF YOUR PIPE IS 1 1/4 OUTER DIAMETER THEN MOST LIKELY IT IS A 1 INCH PIPE, SO TRY THE 1 INCH CAP.
