Question 1

I have a retractable water hose that has a weak spot that wants to bend.  I am looking for something to put on that weak spot.  Will this work?.

Accepted Answer

It is designed to protect hydraulic hose.  The particular one you linked to is 1 3/8 inch I.D.  That would be a very large water hose.  A smaller diameter one would be better suited.  The other problem is being designed for hydraulic hose protection it is flexible bit not real flexible.  Quite stiff actually.  If you are wanting it to go on a hose that retracts into a reel it would not be a good choice as it would not retract past the point of the start of the spiral wrap.

Question 2

What's the smallest ID this will fit?

Accepted Answer

Not really certain what you are precisely asking but will give it a go.  The inside diameter on the product states 1 3/8 inch inside diameter but it is also listed as 40 mm which is how they are actually sized: in millimeters. (See chart below.)  You can certainly put anything less than 2.0 inches O.D. in side the wrap ( I have it on larger hoses) but if it is much smaller than 1 3/8 O.D. hose there will be a lot of movement and the wrap will not hold firmly on the hydraulic hose.  Some wear will result and you may not have the best result.  I would not recommend this size be used on any hydraulic hose that has an O.D. less than 1 3/8 inches due to the slop that will occur inside the wrap.  The wrap is designed to be spooled/wrapped onto the hose so that it is relatively tight and has expanded a bit for a snug fit.  If you have a smaller O.D.  hose that you are concerned about just select a smaller split wrap protector.  It comes in a lot of different sizes.   I use 5 different sizes depending upon which size hose I am providing protection.

NFSGX63	2.0"			       2.05" to 2.95"
NFSGX75	2.4"			       2.56" to 3.80"
NFSGX90	2.83"			3.15" to 4.30"
NFSGX110	3.43"			3.80" to 4.90"
I do not know why they use an OD dimension on the description (Pre-cut Spiral Wrap Hose protector 1.5"OD, 12' Length, Black) here on AMAZON when the ID dimension is the spec that is important.  Just look at the picture's label for the ID of the product.  I have been VERY happy with the product and it is much less expensive than in the hydraulic stores.  In addition it is made in the USA and most of the rest are made in the PRC.
