Common Specications (applies to all CPF ttings in this datasheet)
DESCRIPTION
CPF is an improved cone type tting system that adds a unique o-ring sealing system which permits leak free con-
nections without tools. CPF ttings can be directly connected to ¼" medium pressure cone type ttings from other
manufacturers*, provided that wrenches are used to complete the connection. The ttings of the CPF system have been
designed and tested to comply with ASME B31.3-2008, Chapter IX: High Pressure Piping.
U.S. Patent No. 8,794,677

HiP: 1/4" Female and Male Medium Pressure (LF4 & LM4 series)
Autoclave Engineers: 1/4” Female and Male Medium Pressure
(SF250CX series)
PERFORMANCE
Maximum Allowable
Working Pressure (MAWP):
10 000 psi / 700 bar / 70 MPa
Finger-tight: -20 to 50°C
Wrench-tight: -40 to 150°C
Minimum Hose Bend Radius:
1.0" (25mm)
Most ttings thoughout this document meet the MAWP
specicaton of 10000 psi / 700 bar / 70 MPa. Exceptions are
labeled with an icon (
pressure rating.
Non-Crystal MP adapters require wrench tightening.

CONSTRUCTION
Thread Type: 7/16-20 UNF 2B
Cone Angle: 60°, nominal
Fittings: High Strength 316 Stainless Steel
Hose: Polyamide core
with urethane jacket
External Hose Diameter: 0.235" (6 mm)
Internal Hose Diameter: 0.08" (2 mm)
Hose Weight: 0.0179 lbs/ft (26.6 g/m)
CPF Female O-rings: AS568A-012, Viton® 80 or 90
#3981
O-ring Lubricant: Molykote® 55
RECOMMENDATIONS
Thread Lubricant: Use a process compatible uid
Wrench Torque: 100–140 in-lbs (11.3–15.8 Nm)
Hose is not compatible with dioctyl sebacate uid.
CAUTION: To achieve CPF maximum allowable working
pressures no o-ring substitutions are allowed.
If a torque wrench isn’t practical to use,
hand tighten then tighten an additional
20 degrees using a wrench.
Note Regarding CPF Hose (MPH-X)
Due to the wide variety of operating conditions it may be subject to, Crystal Engineering, as well as Distributors and
Representatives of Crystal products, do not warrant that this hose is suitable for any specic use. This hose is not for use with
compressed natural gas (CNG).
When used with gases, fuels (liquid or gas) and refrigerants, permeation (i.e., seepage) will occur from inside the hose. In
enclosed or unventilated spaces this permeation may result in high concentrations of vapors which are potentially ammable,
explosive or toxic.
Care must be taken to protect hoses from snagging, kinking, bending smaller than the minimum bend radius, and cutting. Any
hose that has been damaged in any way should be removed from service and discarded immediately.
