Ordering Information
For an order or quotation for a CL Leak, please provide the Part Number and confirm the Outlet Fitting for connection to your system or part. It is also necessary to specify the Gas and specific Leak Rate with your preferred leak-rate units. In addition, the Manufacturing Variance ("Tolerance") that you can allow on that Leak Rate should be specified as +/- 40% (the normal allowance), or as +/- 15% (the "Special-Range Variance"), for which there is an additional cost and an "-SR" added to the part number. An example specification is 2.0x10-5 atm-cc/sec +/- 40%. In all cases, the leak rate provided will be as close as we can make it to your specified rate, and the actual rate, as calibrated, will be recorded on the Calibration Tag and the Certifications.

Part Number Build-Up
The CL Series Part Numbers are constructed as follows:
CL-X-BB-YYYY-ZZZZ-FVO
where X = the code for the Leak Rate Range required,
where BB = Gas to be used,
where YYYY = the fitting required*,
where ZZZZ = the Reservoir required,
and FVO = the Fill Valve Option.
A fill valve is required for many gases other than Helium, Argon, Nitrogen, Carbon Dioxide, and Air. Due to the high gas depletion rates for leak rates of 10-4 and 10-3 atm-cc/sec, these leaks must also have a fill valve for all gases. Additionally, leaks in the 10-3 range, and often in the 10-4 range, have an integral pressure gauge installed to monitor the residual pressure and indicate when filling is necessary.
* Except for Helium leaks, the fitting for 10-7 atm-cc/sec and smaller leaks must be a VCR or Conflat flange. If you require a different fitting, an adapter can be purchased.

Note: Larger and smaller flow rates are possible. However, with leaks smaller than 10-6 atm-cc/sec there is increased risk of plugging of the capillary and precaution in use should be taken. For all leak rates, the leak's shut-off valve should be kept in the closed position when the leak is not in active use.
A fill valve is required for H2, CO, CH4, SO2, NE, KR, D2, XE and HE3. Mixed gas leaks may also need additional calibration points.
