Type: One Way Shut-Off

• Socket is valved, shutting off supply line at disconnect. Plug is un-valved, exhausting downstream line at disconnect. Install socket on pressure side of line.

Interchangeability:

• Standard industrial interchange design, most widely used in industry.
• 3 and 5 Series Automatic water service comply with A-A-59439 (formerly MIL-C-4109F).
• 3-4-5-6 SERIES MEET ISO 6150-B, ANSI(NFPA)T3.20.14-1990. IN ADDITION, SV SOCKETS MEET ISO 4414.

Rated Pressure:

• 300 PSIG; Vacuum to 27" Hg (connected). Contact Foster for higher pressure applications.

Manual:

• Socket sleeve must be manually retracted to connect and disconnect.

• Low cost, general-purpose coupler
• Positive locking mechanism
• 65% more ball retention
• Precision leak-proof seal and heavy steel sleeve.

Automatic:

• Inserting the plug into the socket automatically retracts the sleeve to connect. Manually retract the sleeve to disconnect.

• One-hand operation
• One-piece sleeve with rear crimp
• Precision leak-proof seal
• Long-wearing pin-type locking mechanism
• Greater plug contact

Features:

• High flow capability for a small coupler
• Precision leak-proof seal
• Positive locking mechanism
• Sockets other than standard have color-coded seals: Water (Blue), Steam (Black), Silicon (White), and Heat (Red)
• High flow metal valves.
• Precision molded seals form a "bubble tight" seal for reliable operation within rated working pressures. Nitrile (Buna-N) seals are standard. EPDM, Viton, and Neoprene seals are available as options.
• Proven ball locking mechanism with large numbers of stainless steel locking balls evenly distribute the load to resist wear and provide positive connections and allow a swiveling action to reduce hose torque.
• Integral sleeve guard protects the sleeve and resists accidental disconnects for the "SG" series.
• Knurling and/or grooves on the sleeve provide a gripping surface for ease of operation.
• Wide range of body sizes, materials, options, and end terminations are available to meet specific needs.
• Accepts Industrial Interchange Plug.

Safety:

To connect, insert plug and pull sleeve forward. To disconnect, push sleeve back while rotating first counter clockwise and then clockwise. As sleeve goes back, supply line is shut off, downstream line is exhausted, and plug is released. Remove plug.

• 100% safety
• Connect and disconnect at "0" pressure
• Plug locked before air is turned on and downstream line is exhausted before plug is released, completely eliminating hose whip
• Tested to 1,000,000 operations with no leakage
• Special lubrication eliminates dry breakaway

Connection Sizes:

• 1⁄8" to 1" NPT
• 1⁄8" to 1" Hose Barb (Hose clamp required. See page 200 for Python hose clamps)
• 1⁄4" to 1⁄2" Push-on Hose Barb (Clamps not required when used with Push-On Hose. See page 369 for Push-On Hose)

Options:

• Ball Lock (BL) – Locks manual socket against accidental disconnect. To connect, align ball with slot. After connection, rotate sleeve to lock. To disconnect, realign ball with slot and retract sleeve.
• Sleeve Lock (SL) – Locks automatic socket against accidental disconnect. To connect, align notch with slot. After connection, rotate sleeve to lock. To disconnect, realign notch with slot and retract sleeve.
• BALL CHECK PLUG – Eliminates hose-whip at disconnect by checking the rapid flow of downstream exhaust air.
• SWIVEL PLUGS – Free swivel under pressure. Eliminates hose twist on end drop applications such as blow guns, air tools, etc.

Operation:

Sleeve type couplings are widely used to connect air and low pressure fluid lines. Their compact and economical design uses a ball locking mechanism consisting of captive stainless steel balls that engage the locking groove on the mating plug. The sliding spring-loaded sleeve on the socket must be manually retracted in order to connect or disconnect the plug.

Material:

Brass body and socket end, zinc-plated steel sleeve.

Interchangeability:

Complies with ANSI/NFPA T3.20.14-1990 & ISO 6150-B.
