Crystal Pressure Fittings

Product catalog summary

Overview: The document is a technical data sheet for Crystal Pressure Fittings (CPF), detailing specifications, performance, construction, and recommendations for use. It includes various types of fittings and adapters, along with their specifications and part numbers.

Specifications: CPF fittings are designed to comply with ASME B31.3-2008 standards for high-pressure piping. The maximum allowable working pressure (MAWP) is 10,000 psi (700 bar/70 MPa). The fittings are made from high-strength 316 stainless steel, and the hoses have a polyamide core with a urethane jacket.

Performance: The fittings can operate at temperatures ranging from -20 to 50°C when finger-tight and -40 to 150°C when wrench-tight. The minimum hose bend radius is 1.0 inch (25 mm).

Construction: The thread type is 7/16-20 UNF 2B with a nominal cone angle of 60°. The external hose diameter is 0.235 inches (6 mm), and the internal diameter is 0.08 inches (2 mm). The hose weight is 0.0179 lbs/ft (26.6 g/m).

Recommendations: Use a process-compatible thread lubricant and apply a wrench torque of 100–140 in-lbs (11.3–15.8 Nm). Non-Crystal MP adapters require wrench tightening. O-ring substitutions are not allowed to maintain maximum pressure ratings.

Warnings: The CPF hose is not suitable for compressed natural gas (CNG) and is not compatible with dioctyl sebacate fluid. Permeation may occur when used with gases, fuels, and refrigerants, potentially leading to hazardous vapor concentrations.

Fittings and Kits: The document lists various fittings, including NPT, BSP, M20, and AN4, along with their dimensions and part numbers. It also includes complete fitting kits for NPT and BSP configurations.

Additional Information: The document provides quick links to navigate different sections, including CPF, NPT, BSP, M20, Transmitter, Tube, AN4, Pump Adapter, and Non-Crystal Adapters.

Crystal Pressure Fittings CPF Common Specifications (applies to all CPF fittings in this datasheet) | DESCRIPTION CPF* is an improved cone type fitting system that adds a unique o-ring sealing system which permits leak free connections without tools. CPF fittings can be directly connected to W" medium pressure cone type fittings from other manufacturers*, provided that wrenches are used to complete the connection. The fittings 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) Quick Links Click a Category to Navigate to its Page Most fittings thoughout this document meet the MAWP specificaton of 10000 psi/700 bar/70 MPa.

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) 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 specific 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 flammable, 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. Autoclave Engineers Fluid Components is a division of Snap-tite, Inc.
