NRAMOOS Self-Healing Injection Ports & 20mm Filter Stickers Kit — 100 Rubber Ports + 120 Synthetic Filters, Autoclavable Seal

NRAMOOS supplies a kit of 100 self-healing rubber injection ports and 120 synthetic 20mm filter stickers designed to help maintain sterile airflow and resealable access for jars and vials used in home or lab cultivation.

This kit combines durable rubber ports with breathable synthetic filter stickers so you can maintain a controlled, contaminant-resistant environment in containers requiring periodic injections or gas exchange. The components are built to resist heat and pressure, fit common wide-mouth lids, and simplify routine inoculation and ventilation tasks for hobbyists and professional users alike.

How do these self-healing injection ports simplify repeated inoculations?

The rubber ports are made from resilient elastomer that reseals after needle withdrawal, reducing the need to replace closures and minimizing contamination risk. They are sized for typical stopper openings and designed for repeated use.

• 100 rubber ports (13.2mm diameter) that accept standard needles
• Elastomeric material reseals after puncture for multiple injections
• Easy press-fit installation into jar lids or vial holes
• Compatible with liquid and solid-filled containers

What protection do the synthetic filter stickers provide?

The 20mm synthetic filter stickers allow air exchange while blocking particulates and microbes; they’re useful where breathable ventilation is needed without exposing contents to contaminants. They adhere to cleaned lid surfaces for straightforward application.

• 120 filter stickers, 20mm diameter for wide distribution
• Filters airborne particles down to ~0.3 µm for improved air quality
• Adhesive backing sticks to clean, dry metal or plastic lids
• Useful for jars used in incubation, colonization, or storage

Will these components hold up to sterilization and handling?

Yes — both parts are selected to tolerate heat and pressure commonly used in sterilization processes. The filters and rubber ports maintain structure after autoclave cycles when used according to standard practices.

• Heat- and pressure-resistant materials suitable for autoclave environments
• Filters engineered to preserve airflow after sterilization
• Ports retain elasticity and sealing performance after repeated use
• Store unused stickers and ports in a clean, dry place to preserve adhesive and elasticity

Who is this kit for?

This NRAMOOS kit is intended for home cultivators, mycology enthusiasts, laboratory technicians, and anyone who needs reliable, resealable access and filtered ventilation for jars or vials. It’s a practical, cost-effective option for projects that require sterile injections, gas exchange, or occasional sampling without replacing closures after each use.
