Caplug Threaded Plastic Plugs from SkyGeek are specially designed for use on flared JIC fittings. The plugs are part of the PD series and are made of durable materials that allow for a seal at low pressure requirements. The plugs go on quickly and only require finger tightening to form a tight seal. They can be used to seal 37° flare fittings without gaskets and are a great accessory to keep in your toolbox.
