Puncture Direct is a liquid sealant that is injected into tires through the valve stem. It forms a protective layer inside the tire that seals any punctures or leaks caused by nails or other objects. When an object punctures the tire, the sealant is forced into the hole by air pressure to create a permanent rubber seal. Puncture Direct seals all leaks in tires, eliminating underinflation caused by rim leaks, valve stem leaks, or porosity issues. This extends tire life, reduces fuel consumption and wear, and improves safety.

1. What is Puncture Direct?
1
Puncture Direct is a high performance
Ethylene Glycol adhesive liquid
containing tiny rubber particles
Injecting into an ordinary tyre
turns it into a
self-sealing tyre
This does 2 things:
 It seals punctures the instant they occur
 Eliminates under-inflation by sealing all leaks

2. How Does It Work ? 2
Puncture Direct is injected through the
tyre’s valve and forms a protected
layer on the inner tread area of the
tyre.
A puncturing object (a nail)
enters the sealed tyre.
Puncture Direct is forced into
the hole by internal air
pressure forming a
permanent rubber seal.

3. About Tyre Sealants 3
Tyre sealant was originally developed by the
military to make tyres...
Bullet Proof !

4. About Tyre Sealants 4
Sealants have been
further developed for the
commercial and domestic
market as a puncture
proofing product

“A tyre sealant was
featured on BBC TV’s
Tomorrows World
as a potential life
saving device.”

5. Under-inflation 5
… is a tyres No.1 ENEMY
It is the major reason for
blowouts and also creates:
 overheating
 excessive tyre wear
 excessive fuel consumption (due to rolling resistance)
 reduction in resistance of punctures and cuts
Under-inflation is caused by:
rim leaks… valve stem leaks… porosity/migration leaks
Under-inflation has caused
this tyre to wear on the outer
edges of the tread, leaving
the central tread area far
less worn.

6. Under-inflation 6
Puncture Direct
Seals ALL Leaks !
thereby
eliminating under-inflation
“Correct tyre pressure is the most important factor in tyre life.
Under-inflation should never be permitted.” Goodyear
“Correct tyre pressure is the most important factor in tyre life.
Under-inflation should never be permitted.” Goodyear
“Surveys by tyre service engineers show that at least
25% of all tyres examined are under-inflated.” Dunlop
“Surveys by tyre service engineers show that at least
25% of all tyres examined are under-inflated.” Dunlop

7. Effects of Under-inflation 7
Based on a 36psi tyre, tested and road proven by Shell Research Laboratories
Pounds under-inflated % tyre tread loss Lost fuel economy
5lb (15%) 22% 3.10%
7lb (20%) 28% 4.40%
10lb (27%) 37% 6.25%
If an average lorry tyre is under-inflated
by 15 pounds, this represents an:
Increase in tyre wear - 20%
Increase in fuel use - 3%

8. Puncture Direct Saves Money
8
Example
A lorry has 1 puncture and 1 blowout per year, giving 4
hours of downtime @ £45 per hour.
No. of tyres: 12 (11-22.5)
Cost of tyre: £200 each
Cost of fuel: £30,000 per year
Under-inflation: 15lb per tyre
With Puncture Direct fully installed (from as little as £240)
savings would be more than £1,800 per year
“A single flat tyre can cost more
than a complete Puncture Direct treatment.”
“A single flat tyre can cost more
than a complete Puncture Direct treatment.”

9. How Effective is Puncture
Direct? 9
Successfully tested by RAPRA
(Europe’s leading Rubber And Plastics Research Association)
Tested to ECE Regulation 30 Standard:
 tested to speeds of up to 120) (194 kph)
 can withstand 4 times maximum pressure loading
after puncture has been made
Manufactured in the United Kingdom (UK)
(by Puncture Direct Limited)

10. Additional Benefits 10
 Inhibits rust and corrosion of rims and steel belts.
 Protects against dry rot and improves retreadability.
 Is environmentally friendly, non-hazardous and
non-flammable.
 Does not void tyre manufacturers warranty.
 Maintains the right air pressure in your tyres.
 Protects and conditions tyre casings.
 Can be easily rinsed out with water.
 Improves safety.
 Reliable for entire tread life of tyre.
