The John Guest Plastic Half Cartridge provides a quick, efficient and easy way of securing a Speedfit push-in connection into a wide variety of original equipment. As the cartridge requires low insertion loads it is suitable for many different housing materials.


This Half Cartridge includes the following three components:

• A gray collet or gripper
• An EPDM o-ring
• A gray plastic body with stainless steel teeth.

As with all Speedfit products, the push-in connection can be used on plastic or soft metal tubes in both inch and metric sizes. The cartridges are suitable for a very wide selection of original equipment including manifolds and multi-connection points and, because they are produced in food grade materials, Drinks Dispense and Water Purification equipment.

As Plastic Half Cartridges are intended for use by Original Equipment Manufacturers they are only supplied in bulk quantities.
