Zirc Tank – What is it in Vaping?

Definition

A Zirc Tank is a rebuildable or pre-built atomiser reservoir made from zirconia ceramic—referred to as “zirc” by Australian vapers—designed to hold e-liquid while withstanding high heat and acidic flavours. Unlike standard glass or polycarbonate tanks, zirc offers superior crack resistance against citrus or menthol juices and does not impart any metallic taste. Its primary purpose is to provide a durable, flavour-neutral chamber that extends coil life and supports both Nicotine“>zero nicotine and higher-strength e-liquids.

Technical Details

Zirc tanks are machined from yttria-stabilised zirconia, an advanced ceramic rated to 1,000 °C, ensuring zero thermal expansion at normal vaping temperatures. Wall thickness typically ranges 1.5–2 mm, yielding 4 ml to 5 ml capacity under TPD limits. Threading is usually 510-compatible, with a 25 mm base diameter matching popular mods. Variants include straight and bulb Zeus Tank-style sections, plus hybrid “zinc alloy” caps for drop protection. Some manufacturers integrate Ohm“>zero ohm reading plates for dry-hit prevention, while others swap zirc for PCTG windows to reduce cost. All are pressure-fit with food-grade silicone O-rings rated to 70 °C.

Usage & Tips

• Priming:Dripjuice directly onto the ceramic walls to eliminate initial wicking delay.
• Cleaning: Rinse with warm water only; ultrasonic baths can micro-crack zirc.
• Common issue: Over-tightening the top cap may chip the ceramic—finger-tight plus a quarter-turn is enough.
• Safety: Inspect for hairline cracks after drops; sharp edges can form. Always pair with a zinc alloy cage or bumper if you’re prone to knocks.
• Storage: Keep away from diamond-coated coil jigs—zirc is scratch-resistant, not scratch-proof.

History & Context

Zirc tanks entered the Australian market circa 2018 as high-end upgrades for the Zenith Tank series. Early adopters loved the crack-proof promise for “killer kustard” citrus blends, and today zirc sections are mainstream, sold alongside zero nicotine shortfills in most Aussie vape shops.
