The Value packs are designed to let you get the most for your money by sizing the packages to fit in USPS Flat Rate shipping options. I always shake my head when some one orders just one or two of the smallest fittings and they are paying more for the postage than they paid for the fittings and then a week or two later they order a few more. So with this product I am essentially suggesting How many of any one size I can easily fit into a flat rate envelope.
If you still want to order smaller numbers of uniseals, you can do so on the Uniseal page.
Plumbing through tank walls is made much easier and less expensive using a Uniseal®. Unlike bulkhead fittings a Uniseals can handle slight irregularities or curvatures without leaking. With a sturdy backing, a Uniseal® can even be plumbed through liner.
Bulkhead fittings often have limited connection options and force the use of extra threaded fittings to connect the pipes. Bulkhead fittings usually cost more than Uniseals.
Instructions for installing Uniseals
- Cut hole to the proper size for the Uniseal you are using.
- Insure that the hole is clean cut with no sharp edges. Irregularities could cause poor sealing and ultimate leakage.
- Insert the Uniseal into the hole with the wide side facing the pipe to be inserted.
- Make certain that the pipe end to be inserted is clean cut. sand the edges so that there are no sharp points.
- Using rubbing alcohol or slimy water, lubricate the outside of the pipe end to be inserted (the manufacturer recommends detergent and even Aquatic Eco systems says windex but both these could be bad for the fish so I usually just use water or rubbing alcohol since it will evaporate,) then push the pipe through the Uniseal from the large flange side. The co-efficient of friction of the rubber holds the pipe tightly in place.
I have found that using a T on the end of the pipe being pushed through provides a good handle to push against since pushing the pipe through a Uniseal® is the only difficult part about the whole procedure. Make sure before deciding to use a Uniseal® that you will have the space and angle/leverage to push the pipe though and that the hole will have enough clear space around for the flange of the Uniseal® to seat properly (don’t drill the hole too tightly into a corner.)
A Uniseal® can even be plumbed into a pipe, but the pipe having the Uniseal® hole cut in it must be enough larger than the Uniseal® being installed that it will still seal properly.
Uniseals are made for low pressure applications and if you are putting any mechanical pressure against the pipe that is going into a uniseal it could cause leaking, make sure your pipes are adequately supported and you are not torquing things too much to get it all to fit (I do like the rubber couplers used near a uniseal to give a little extra play and not require “perfect” angles to make things fit nice.)
Sizes listed are the pipe sizes the Uniseal® work with. For Example, if you are using 1″ Schedule 40 pipe or PVC drinking water pipe, then you want the 1″ uniseal. I also list the size hole saw needed to cut the proper hole for each size uniseal.
|1/2″ Uniseal® $1.80 each ($1.57 each when you buy a ten pack)||3/4″ Uniseal® $1.85 each ($1.58 each when you buy a ten pack)||1″ Uniseal® $2.00 each||1 1/4″ Uniseal® $2.27 each|
|(1.25″ holesaw size)||(1.25″ holesaw size)||(1.75″ holesaw size)||(2″ holesaw size)|
|1 1/2″ Uniseal® $2.57 each||2″ Uniseal® $4.30 each||3″ Uniseal® $5.34 each||4″ Uniseal® $6.72 each|
|(2.5″ holesaw size)||(3″ holesaw size)||(4″ holesaw size)||(5″ holesaw size)|
|6″ Uniseal® $9.95 each|
|(7″ holesaw size)|
Pipe sizes listed are the “Nominal” pipe sizes that match the Schedule 40 PVC Outside Diameter here in the USA where the Uniseals are made. The “Nominal” size does not indicate the outside diameter of the pipe. Pipe sizes are NOT the same world wide. While it seems the pipe sizes in the USA and Australia are compatible some parts of Europe are NOT and I do not know where else. Please do some research into pipe sizes before ordering. I do not refund the shipping or pay for the return shipping on uniseals since it normally costs more to ship them than it costs for the parts themselves.
