GRA-TEC MODULAR DESIGN CONCEPT

Four proven components brought together to provide unmatched flexibility to solve your system and
component designs.

SPUD 1. GRA-TEC MALE FITTINGS: The proprietary GRA-TEC male end has two grooves on a hollow cylindrical end of a fitting. The other end of the GRA-TEC male fitting can be adapted to accept tubing, hose, male or female pipe threads or a wide selection of other connections.	O-RING 2. O-RING SEAL: The first groove on the GRA-TEC spud accepts an elastomeric O-Ring which provides a leak-proof seal when the fitting is assembled. O-Rings are available in a variety of materials and provide reliable seals for most fluids and most fitting applications.
RETAINER 3. RETAINER CLIP: The secondt groove on the GRA-TEC spud accepts a retainer clip which holds the assembled fitting together. Clips are available in two styles, wire clip (to 250 PSIG) and flat clips (to 2500 PSIG).	CONNECTOR 4. GRA-TEC FEMALE CONNECTORS: A variety of female connectors make elbows, tees, crosses and various combinations. The GRA-TEC male fitting is pushed into the female connector and the retainer clip is inserted. PUSH, CLIP; and the connection is made in 5 seconds.

HERE'S HOW IT WORKS: Snap your choice of GRA-TEC fitting into the connector block, (positive O-Ring Seal). Next, insert the GRA-TEC retainer clip to make the fitting a locked connection. The result - a 1500 PSI Class fitting in brass (4:1 safety factor) suitable for most vacuum or pressurized applications.

PUSH - GRA-TEC male fitting with O- Ring seal pushes into GRA-TEC female connector.

CLIP - Retainer clip installs by hand to hold the two components together. This joint is rated for a working pressure of 1500 PSI!

Only GRA-TEC fittings offer all these advantages: 1. Component assembly and disassembly without tools! 2. Circuitry can be pre-assembled and tested on the work bench, then installed in close fitting consoles without wrenches.

3. Can be installed in tight corners and small openings where it would be impossible to install conventional fittings. 4. Production test work is greatly accelerated with pre-assembled tubing lengths which can be snapped together at the test bench. 5. Elastomeric seals act as vibration dampers throughout otherwise rigid circuits.

6. Eliminates leaks due to torsional forces normally left in circuits when tightening rigid tubing. 7. Joint flexibility reduces the need for precision location of circuit components. 8. Makes available many thousands of useful fittings not listed in commercial catalogs.

Any fitting configuration assembles in seconds.
