Hiland Quartz Glass Tube Replacement for 4-Sided Pyramid Patio Heaters — 49.5" Tall x 4" Diameter, Single-Piece Durable

Hiland SGT-GLASS is a single-piece 49.5" tall, 4" diameter quartz glass tube designed to replace the glass element in most 4-sided pyramid (flame) patio heaters.

This replacement quartz tube restores the visible flame column and protective enclosure on compatible 4-sided pyramid-style outdoor heaters. Built to match the dimensions and fit of many current models, it serves as a direct swap for single-piece tubes and can also substitute for two-piece assemblies in those heater designs. Note that this component is intended specifically for 4-sided units and is not compatible with 3-sided heater models.

Will this quartz tube fit my Hiland pyramid heater?

Measure your existing glass tube or check the model compatibility before ordering. The Hiland SGT-GLASS measures 49.5 inches in height and 4 inches in outer diameter and is compatible with several Hiland model numbers and reference parts.

• Exact dimensions: 49.5" tall x 4" diameter
• Fits HLDS01-GTHG and HLDS01-GTSS models
• Replaces reference parts 584736, 639564, PH08-SB, and HLDS01-GTPC
• Works as a single-piece substitute for some two-piece tube assemblies

How do I replace the glass tube safely?

Always follow your heater manufacturer’s instructions and allow the unit to cool completely before starting. Handle the quartz tube with clean gloves or a soft cloth to avoid fingerprints and oils that can cause hot spots; secure the tube in the enclosure using the heater’s original clamp or retaining ring.

• Power off and let the heater cool fully before touching the tube
• Wear gloves or use a lint-free cloth when handling the tube
• Confirm seals and retainers are present—this product does not include rubber rings
• Test for a snug, wobble-free fit before lighting the heater

What should I expect in terms of durability and care?

Quartz glass is chosen for its thermal resistance and clarity, but it still requires careful use. Avoid sudden temperature changes, impact or abrasive cleaners; routine cleaning with a mild glass cleaner and soft cloth keeps the flame visible and the tube performing well.

• Resists high heat but avoid thermal shock from rapid cooling
• Clean with non-abrasive glass cleaner and a soft cloth
• Inspect for cracks or chips before each season
• Replace immediately if damage is found to maintain safe operation

Who is this replacement tube for?

This Hiland SGT-GLASS tube is intended for owners of 4-sided pyramid or flame-style patio heaters who need a direct-fit quartz replacement. Ideal for DIY maintenance, rental-property upkeep, or commercial venues using compatible Hiland models, it provides a straightforward way to restore the visible flame and protective tube on outdoor heaters that use the listed dimensions and reference numbers. Remember: it will not fit 3-sided heaters and does not include the rubber retaining ring, so verify your heater’s configuration before purchasing.
