The Most Durable, Fully Sterilizable 41mm Plant Collars for Serious Growers

PermaClone™ 41mm collars are engineered for growers who demand predictable, contamination-free cloning cycles in aeroponic and hydroponic systems. Unlike traditional neoprene or foam pucks that absorb moisture, harbor microbes, and degrade after a few cleaning cycles, PermaClone collars are molded from a medical-grade polymer blend designed specifically for heat sterilization, chemical resistance, and long-term durability.

If you’re using Botanicare® Power Cloner®, Clone King®, or any system accepting 41mm inserts, these collars give you a perfect stem fit, microbial resistance, and complete compatibility with dunk-based or heat-based sterilization methods.

These are the only collars on the market engineered to be microwavable, oven-sterilizable, pressure-cookable, and autoclave-safe—all while lasting 5+ years under daily use.

⭐ Key Benefits

• Heat sterilizable: microwave, dry heat (300°F), pressure cook, autoclave

• Chemical resistant: safe with bleach, peroxide, hypochlorous acid, Physan 20, Zerotol, etc.

• Closed-cell, non-porous polymer prevents root penetration & pathogen harboring

• Ellipsoid compression design reduces stem pinching

• Central gap ensures all surfaces receive sterilizer contact

• Long-lasting: 10+ year material life, backed by a 5-year warranty

• Perfect fit for 41mm sites across major systems
