These cups are are manufactured  in the U.S.A from Borosillicate glass which is most commonly referred to as PYREX and  known for having very low coefficients of thermal expansion, making them resistant to thermal shock. Each cup is size labeled to ensure that the welder isn’t wasting time trying to find the correct size cup. Every cup is oven annealed to ensure that the life of the cup is maximized.

These kits are great for Getting that clear view of what you are welding.  It doesn’t matter if its mild steel, stainless or aluminum you can keep a clear view of the weld all the time.

Description

The glass is borosilicate, most commonly known as Pyrex. (Pyrex is a brand name)  This is the same glass that your kitchen cookware is made out of,  and laboratories use for general glassware.  The reason that we chose Pyrex is because of it’s good thermal properties and durability.  Pyrex is known for it’s impact resistance and also thermal shock resistance.  The working temperature of the cup is 914F (490C) maximum.  The reason that we don’t recommend walking the cup is because of the higher temperature when the glass contacts the metal next to the weld pool it will cause premature stress (hot spot) on the glass, and will cause premature failure.  As long as the cup isn’t resting on the metal and there’s no contact with the weld there’s no concern for premature breakage.  The other consideration is, there is always gas flowing past the cup which keeps the cup cool.

Stress is introduced into the glass starting at 950F (510C).

The O-rings are high temperature silicone that’s rated to 400F (204C).  They are very chemical resistant and we haven’t had one replaced because of melting.
