Footballs (Soccer balls) Air Pressure
We recommend – always use proper air pressure for your footballs (soccer balls). Do not over or under pressurize a ball. Use the manufactures recommended air pressure that is printed on most balls. Most footballs have a pressure rating of 6 to 8 lbs. or 0.6 or 0.8 BAR. It is recommended that you use a pressure gauge to measure the exact amount of pressure in a ball after inflating and before use.
BAR or PSI or LBS?
Some footballs have recommended pressure values indicated in BAR while others have the values indicated in PSI or LBS. To convert the pressure values, use the following formulas:
To convert BAR (Kgs) to PSI (Lbs.):
Answer = 14.5037 X The amount of BAR (Kgs)
For example: A footballs has a recommended pressure of 0.6 BAR labeled on it. To convert BAR in Pounds Per Square Inch (PSI), multiply 0.6 times 14.5037. The answer is 8.7 PSI or Lbs.
To convert PSI (Lbs.) to BAR (Kgs):
Answer = .068948 X The amount of PSI (Lbs.)
For example: A footballs has a recommended pressure of 7.9 Lbs. (PSI) labeled on it. To convert Pounds Per Square Inch (PSI) into BAR, multiply 7.9 times .068948. The answer is 0.545 BAR.
Inflating your Footballs (Soccer Ball)
Footballs lose air pressure over time. Sometimes over a few days (footballs that use butyl bladders keep air pressure longer than balls that use latex bladders). Be sure to check the pressure frequently to make sure the ball is properly inflated. Therefore, invest in a good ball pump, have a supply of inflation needles and use a low pressure gauge to measure for proper inflation.
Before you first inflate a footballs, place a couple drops of silicone oil or silicone lubricant spray or glycerin oil into the valve. You can purchase one of the oils or spray at your local hardware store. Using one of the lubricants will improve the life of the valve and lubricate the valve for easy insertion of the inflation needle.
Always moisten the inflation needle before you insert it into the valve. Preferably, use some silicon oil to moisten the needle. However, some people use spit…yuk, but that is not recommended.
Manufacturers recommend that you reduce the air pressure in your match balls after a game to reduce the amount of stress on the ball seams or stitching. Be sure to inflate the ball back to proper pressure before the match.
