Q: How do you cut a hose sleeve?
A: Cutting your protective sleeve is simple! You can use a sharp high-quality scissors, knife, rotary cutter or a hot knife.

Q: How do I size a sleeve properly to fit the hose?
A: Determine hose OD or hose bundle OD. If needed find the circumference of the hose or bundle of hoses, then calculate diameter. Also assess if the hose or hoses have bends or movement during application as the sleeve will need to be over sized to accommodate. Sizing a sleeve to tight to the hose or bundle of hoses will hinder natural movement of the hose within the sleeve, causing premature hose failure due to possible abrasion. Typically size the sleeve 1 - 2 sizes bigger than your current hose or hose bundle OD.

Q: What is the difference between inner diameter (I.D.) and outer diameter (O.D.)?
A: The Inside Diameter is the inside measurement from one inside edge to the other inside edge on the interior of a hose, tube, pipe or other object. It is often abbreviated as I.D.

The Outside Diameter is the outside measurement from one outer edge to the other outer edge of a hose, tube, pipe, or other object. It is often abbreviated as O.D.

Different products require specific measurements. For example,

Fire sleeve, always measured by inner diameter.

Heat Protection tube, always measured by inner diameter.

Fiberglass braided sleeving, always measured by inner diameter.

Kevlar briaded sleeving, always measured by inner diameter.

Hydraulic hose textile sleeves, always measured by inner diameter and flat width.

Heat reflective sleeve, always measured by inner diameter.

Q: Temperature Conversion Table

Below, we’ve included the different temperature conversion formulas to make it easier for you to figure out how many degrees Fahrenheit will translate into.

From	To Fahrenheit	To Celsius	To Kelvin
Fahrenheit (F)	F	(F – 32) * 5/9	(F – 32) * 5/9 + 273.15
Celsius (C or o)	(C * 9/5) + 32	C	C + 273.15
Kelvin (K)	(K – 273.15) * 9/5 + 32	K – 273.15	K

Here’s a conversion table that will show you those calculations i Fahrenheit, Celsius and Kelvin.
