Non-spill Flush Face Quick Couplings; Heavy Duty |
The FF49 Series quick couplings provide rugged-flushface
valving for non-spill dry breaks, and allow one-hand
push-to-connect with safety sleeve-lock standard. The
3/8" size meets HTMA dimensional standards while
providing significantly higher pressure containment than
other brands (10,000 operating psi). The 3/4" FF49-6
and FF49-6-12 are rated at 6,000 operating psi and have
a significantly smaller footprint than other brands. Ideally
suited for use in hydraulic hand tools, overhead bucket
hoists, skid-steer loaders, and wherever spillage can
constitute a safety or environmental hazard.

 |
 |
Interchangeable with quick couplings meeting International
Standard ISO 16028 dimensional requirements while
exceeding performance requirements. |
|
Interchangeable with SafeWay’s FFE49, with higher maximum
operating pressure. |
|
3/8" size is available in 303 stainless steel (SF49-3). |
|
Available in 3/8" and 3/4" body size in a wide variety of thread
sizes and types (pipe and ORB standard). |
|
3/8" size meets HTMA dimensional requirements. A black
sleeve and “10,000 PSI MAX” stamping identify this size as
the high pressure model within this interchange. |
|
SafeWay began a running change from zinc and
yellow chromate plating (gold appearance) to ROHS
compliant plating (silver appearance) in 2007. |
|
Provides significantly higher working pressure than couplers we
replace, with equal or better flow. |
|
Flush face valving for non-spill dry breaks with low air
inclusion; and easy cleaning to minimize system
contamination. |
|
Nitrile seals are standard. Seals made of Viton® are
standard in the SF49-3. |
|
|
|
All FF49 Series quick couplings are 100% leak tested. |
|
Unique double seals behind the coupler sleeve prevent contamination
from reaching critical toleranced parts. Reliability
under conditions that would render other brands inoperable. |
|
Maximum flow for quick system response. |
|
Smooth push-to-connect operation will allow connections
against a maximum of 250 psi trapped pressure in the 3/8"
body size; a maximum of 400 psi in the 3/4" body size. |
|
Standard sleeve lock feature prevents unintended
disconnection. |
|
Additional detent (locking) balls greatly improve durability and
increase pressure containment. |
|
Excellent for use anywhere spillage can result in a safety or
environmental hazard. |
|
Heavy-duty steel dust plugs and dust caps are currently available for 3/8" body size male and female halves. |
|
Method of obtaining and presenting performance data
conforms to ANSI/(NFPA)T3.20.2.R2, Hydraulic fluid power
- Quick-action couplings - Test methods. |

Performance Data
The SF49-3 is produced in 303 series stainless steel with Viton® seals standard. Dimensional data is identical to the FF49-3.
Temperature Range: Standard Seals (Buna-N) -40° to +250° F Viton® Option (std. in SF49-3) -15° to +450° F
Vacuum Data: 27.4 inches Hg. both connected and disconnected — all sizes.
Pressure rating (Max. Operating Pressure) is based on Non-Pulsating, Low Cycle applications with essentially steady pressure during the operating cycle.
Please consult factory regarding other applications.
