Tire Chain Net Inflatable Boat Docking Marine Pneumatic Rubber Fenders
Product Introduction
1. Outer rubber of pneumatic rubber fender
The outer rubber layer covering the outside of the fender protects the cord layer and the inner rubber from wear and other external forces. The material has sufficient tensile strength and tear strength to withstand any weather conditions and arduous use. The standard color is black, and Hener can provide other colors upon request.
2. The inner rubber of pneumatic rubber fender
The rubber membrane lining seals the compressed air inside the fender.
3. Synthetic tire cord layer for reinforcement
The reinforcement layer is made of synthetic tire cord commonly used in tires, arranged at an ideal angle to maintain internal pressure and evenly distribute stress, thereby providing a powerful and effective reinforcement.
4. Swivel shackles at both ends of the fender
Place a steel ring on one end (or both ends) of the fender and fix one end of the rope layer.
5. Fender flange
A steel flange is installed on the mudguard, and an air valve or safety valve can be installed.
6. The safety valve of the fender
Fenders with a fender diameter of 2500mm and larger should be equipped with safety valves to release excessive internal pressure when the fender is accidentally over-compressed. Mudguards with a diameter less than 2500mm can be equipped with safety valves as required.
7. The metal fittings of the fender
All relevant metal fittings of the pneumatic fender, including shackles, towing rings, swivels, chain nets, are made of stainless steel, which can resist seawater corrosion.

Notice Of Fender Application And Storage
1. The fender pressure should be kept in the standard pressure
,within the rate of ± 5% range.
2. Often check the pressure , when the pressure drops, Inflate the
fender in time, so as not to affect the normal use of the fender.
3. When connecting the fender with a steel wire rope, the wire rope
should be fitted with a rubber sleeve to avoid damage to the fender
4. Do not touch the fender surface with the the sharp objects , to
prevent piercing the fender. If the fender's surface is damaged, it
will affect the lifespan of the fender.
5. When the fender is in normal use, the fixing points should be
firm, prevent the detachment and wash away the fender. Suspension
of the rope and hook ring should be connected orderly , can’t be in
a mess.
6. If the fender won’t be used in a long time , to clean the fender
surface with fresh water, and place the fender in a dry, cool,
ventilated place, without direct sunshine.
7. When the fender is stored for a long time, the pressure should
be reduced and the fender should be placed far away from the heat
source.
8. Because the fender is rubber product, should try to avoid the
fireworks, not contact with acid, alkali, oil and other organic
solution
9. When the fender is stored, it shall not be folded or stacked,
and don’t stack other objects on the fender.
