The glass tube is made of high-purity quartz, ensuring strength and durability. High-purity quartz glass has a softening point temperature of about 1730°C, providing high-temperature resistance suitable for heaters.
Super easy to install! Simply place the glass tube into the pyramid heater and secure it firmly.
It stands at 49.5 inches tall and has a diameter of 4 inches. This is the perfect size to replace a 4-sided pyramid outdoor heater, ideal for those about 89.4 inches high (not applicable for 91-inch high, 3-sided heaters).
The double-ended open quartz glass tube comes with a black rubber ring. This black rubber ring helps to seal and fix the lower part of the glass tube to the bottom, ensuring a secure fit.
