John Guest’s wide range of brass and plastic push-fit fittings for miniature air and pneumatics offer tool-free installation and an airtight seal. Our unique collet locking design firmly and securely holds the pipe in place without deforming the pipe or restricting flow.
We also offer a unique SuperThread fitting that enables male adaptors to be used with a variety of female thread forms. Our products are suitable for air and pneumatics piping systems up to 10 bar, as well as inert gases, vacuum and potable liquid applications.
