Boundless Terp Pen O-Ring

Maintain the functionality of your vaporizer with the Boundless Terp Pen O-Ring set. This official 5-pack of OEM replacement rings fits securely around the heating chamber of the original Terp Pen and Terp Pen Spectrum. Serving as a crucial gasket, these O-rings create a strictly airtight seal essential for triggering the device's inhale-activated sensor. Replacing worn, stretched, or brittle seals restores restricted airflow and ensures efficient heat transfer for massive vapor production, keeping your device running at factory standards.
