Hydraulic hoses are pretty tough they've got generally a very anti-abrasion
rubber coating on it that will take quite a lot of beating quite a lot of abrasion quite a lot
of rubbing up against other hoses before they will actually start to wear there is a product though
that is available that will protect the hose even more from abrasion from mechanical hits
and knocks you know from gravel and rocks and bits of wood in earth moving tree lopping applications
and this is actually called, we call it spiral safety guard some people call it pig's tail
it's a high-density polyethylene it's actually extruded as a pipe and then it's actually cut
into the spiral after it's extruded while it's still warm to create this very flexible springy
product generally it comes in black but it's also available in red
yellow and blue special order green and comes in many sizes but generally it's
it's designed to suit a small range of hose diameters so this product is actually called
is size 25 but 25 is fits perfectly over a 22 millimeter diameter hose 22 millimeters
is standard half inch SAE 100R2 two-wire so as you can see the product is actually longer
than required but when you actually wrap it you actually lose length so as a rule whatever
the length is between the two shells you multiply this length by about 1.2 and that will leave you a
small margin of error usually it's just a little bit longer um in this case
we've had this wrap on this hose already so it should fit quite perfectly
uh application always start a few inches back you know about 100 millimeters back from the hose
if it's a very long hose it's always best to try and start in the middle
so if for example you've got a one meter long hose cut yourself 1.2 meters of product if you've
got a 2 meter long hose cut yourself 2.4 meters of product the longer it is the more unwieldy it gets
and eventually when it's too long usually it involves two people sometimes three people and
or a machine to help you wrap this hose but it will extend the life of the hose
dramatically and it also makes the hose a lot slipperier as well so good when it's rubbing
up against another hose it's also covered if you're pulling this hose through a machine
pulling rubber hoses through a machine sometimes is a pain but once they're covered
in this it makes the hose a lot slippery and actually a lot easier to pull the hose through
that's what i found anyway in my experience makes the hose a little bigger in diameter and in some
cases that could be a detriment especially if you've got multiple hoses going through
a small hole you may have to enlarge the hole and also protect the hole from chafing so
applying this product you basically need to unwind it and then wind it on
and because it's like a spring you can wind it in the opposite direction it actually opens it
up and makes it bigger and then you can actually move it down or move it up so you can adjust it
short hoses are easy because you could actually do this but if you had a really long hose you
couldn't actually get your wrap your arm around so you've actually got to physically manhandle
this product around and around and around saves the hose
hurts your wrists
because you know as you can see i've got super big wrists
so that's it on the hose still lets the hose bend and flex but it gives it that abrasive
protection on really sharp edges though it will catch all right but if you've got sharp edges
you should do something about them. Anyway so that's a spiral safety guard Hose protection
high density polyethylene available in many sizes and red black blue and yellow
