adjustment

• Dynamic Seals that minimize seal stress to increase

seal life, reliability and sealing pressure

Medical Compressed Gas Connectors

APPLICATION GUIDELINES

z FasTest medical gas series connectors are designed to connect to specic CGA medical gas valves.

z Connectors for respiratory air/oxygen must be kept free from oil and grease.

Use Krytox or approved equivalent lubricant as required.

z Do not connect to a damaged cylinder valve.

z Contact FasTest if the product is damaged, or if you have inquiries on the proper function of the connector.

Do not use the connector until clarication is sought.

z Connectors may only be dismantled by FasTest or trained personnel.

z Do not use excessive force when connecting. See Operating Instructions outlined in this manual.

z Filling gas cylinders is potentially dangerous. Appropriate safety measures must be taken. FasTest is not liable

for injuries to persons or property arising from incorrect use.

z Connectors without an operating loop require additional security by means of safety wire, safety cage, etc.

z When using a quick connector with lling hose, please ensure that the cylinders to be lled are secure.

z FasTest does NOT recommend hanging cylinders from connectors.

Medical Compressed Gas Connectors

INSTALLATION

Step 1

Protect the connector from damage and dirt by keeping it in the original packaging until you are ready to use it.

Step 2

Check that the connector part number and delivery notes (if applicable) comply with the application.

Step 3

Connect the hose securely and leak-tight to inlet or
outlet. Tighten to a max torque of 15 ft-lbs.
A higher torque can result in damage causing leaks when
the system is pressurized. Ensure that the connectors

cannot be damaged when loading and removing the

cylinder (Figure 1).

CAUTION:

!

Do not over tighten.
Over tightening could break connector
and cause injury to operator.

Step 4

Review total connector function:

MediMate CGA 870 and CGA 950 (Figure 2)

• Check leak-tight seal.

• Check handle operation.

• Check seal-face/piston movement.

• Check that marking complies with application.

Medical and Industrial CGA 540 (Figure 3)

• Check leak-tight seal.

• Check that collets open and close properly by
actuating the connector several times.

• Check that marking complies with application.

Note

Avoid lateral forces like short connecting hoses

as this could cause leakage.

MediMate CGA 870 AND CGA 950 OPERATION

Step 1

At the start of each shift:

• Check all connectors for main seal condition.

• Check for smooth operation of the handle before the rst ll.

• Check seal-face/piston movement.

Safety features:

• If the handle is accidentally disconnected under pressure, the sealing piston
will travel with the valve to retain a seal. The piston will retract and return to
its original position once the pressure has dropped below 250 psig.

Figure 6. The piston retains position against valve during

accidental disconnection.
