Valves with Bite Type Ports for Metric Tubing | Parker EO & Parker EO-2
 |
EO flareless fittings for metric tubing are a great choice for leak free connections under various service conditions ranging from sealing high vacuum and small molecule gases, to high-pressure hydraulic fluids. EO fittings’ compact design makes them ideal for plumbing applications in limited or tight space. EO fittings are suitable for applications in subzero as well as elevated temperatures. The exact service temperature rating is determined by the choice of fitting material, and since EO fittings can be manufactured from a wide range of metals, it's compatibility with various fluids, temperatures, and atmospheric conditions is virtually limitless. |

Flareless Fittings
for Metric Tubing
The EO fittings are the most widely used bite type fittings in the world.
The EO progressive ring fitting is a flareless fitting for metric tubing that consists of a body, a progressive ring (ferrule) and a nut. On assembly, two cutting edges of the progressive ring “bite” into the outer surface of the tube ensuring the necessary holding power and seal for high operating pressures.
The EO Body. EO fitting bodies are available in over thirty configurations. The shaped products (i.e., elbows, tees, crosses) are hot forged, then machined to the stringent EO fitting specifications. The forging process used by Parker further improves the strength and metallurgical properties of the fitting material.

Flareless Fittings with Seal
for Metric Tubing
The EO-2 series are high-pressure metric tube fittings combining bite type technology with elastomeric seal on all joints.
The EO-2 fittings are true metric design, conforming to 24° bite-type standards such as ISO 88434-1, DIN 2353 or DIN 3861. The EO-2 fittings come in three series: LL, L and S (very light, light, standard/heavy)
The EO-2 is similar to EO – it consists of a body, a progressive ring (ferrule) and a nut – with an addition of elastomeric seal. The elastomeric seal is located between the inner cone of the fitting body and the tube surface, blocking the only possible leak path.
