With carb caps readily available now, smokers can enjoy low temperature dab hits, ensuring they get the best tasting vapor possible while also getting an overall safer hit. Similar to nails, quartz carb caps are more durable and stronger than standard glass carb caps. Most quartz carb caps come with a flared base that provide a universal fit to any size nail. Many quartz carb caps have a hole that provides ventilation to increase airflow and provide better dab hits.
