You get the features of both the HR® Valve and the Jaco® Fitting on one bag
HR® Features:
- Nickel Plated to resist damage from most aggressive chemicals
 - 1/4" Barbed Stem for attaching tubing, helps keep tubing in place
 - Leak resistant seal in closed position, prevents sample loss. However, when stem is not closed, sample air passes into the ambient air outside valve
 
- Polypropylene molded construction is inexpensive compared to metal fittings
 - Replaceable fluoropolymer faced septum with large area, allows repeated punctures with common lab syringes.
 - Allows reuse of valve by only replacing septum.
 - Option of cap with septum or cap with tubing, allows syringe sample extraction or attachment of tubing by changing caps.
 - Compression ferrule secures tubing onto fitting, which provides a superior grip compared to metal fittings.
 - Standard Jaco® can be used with 1/4" tubing. Jaco® for 1/2" and 3/8" tubing also available.
 - Prices include HR® ON/OFF Valve and Plastic Jaco® fitting for 1/4" OD tubing or septum
 - Use 3/16 ID tubing on barbed stem.
 - Bags with grommets available.
 - Bags with multiple fittings available.
 - Custom sized bags available.

Film Key Features
| 
                                                                         N/A Tedlar® film has very low gas permeation levels for most compounds, and high tensile strength. Bags resist puncture in the field. 2 mil Tedlar® film is an economical alternative to FEP bags. Tedlar® is much less permeable than FEP and is unaffected by the chemical components of gases generally sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans. Continuous use temperature from -98 to 400 ºF (temperature limit depends on fittings used). Required for many EPA testing methods.  |
