Jikoh Mfg., Inc. warranties its Opti-Klear brand sight glasses to be free from material defects
or workmanship for a period of twelve months from date of sale to original purchaser.
We will replace any sight glass deemed defective within that time frame.
Since Jikoh Mfg. Inc., has no control over the use of our sight glass or type of fuel or additive that
the sight glass may be subjected to, we will not replace those sight glasses that have cracked, crazed,
turned cloudy or yellow. There are additives that are added to petroleum fuels, such as, MTBE, BENZENE,
METHANOL, NAPTHA, TOLUENE, XYLENE and others that may adversely affect our sight glasses
or other plastic or rubber components of a petroleum trailer.
Therefore-it is the owner's responsibilty to maintain good maintanence
procedures to replace any component that may be adversely affected by these additives or a combination thereof. Sight glasses should be inspected on a daily basis for any signs of cracking or crazing.
