Schott Bottle Cap Coupon Holder Assemblies
Used with Schott bottles with a DIN GL 45 thread.

 

Adjustable Coupon Holders

Low Pressure or Hand Insertable systems can be used for pressures up to 125 psi. This assembly is commonly used in the water treating industry for coupon insertion through a full port valve. An example of this is in a municipal water pumping station, where leakage during withdrawal of the test coupon would not be critical.

See the SR3000 for more details.

Retractable Coupon Holders

Packing Gland systems are used in environments where ratings up to 1,500 psi are required and leakage is prohibited. These systems do not require line (process) shutdown to insert or withdraw coupons. The assembly is used for coupon insertion through at least a 1" full port valve. A safety cable is provided to prevent accidental discharge.

See the RT4000 for more details.

Retrievable Coupon Holders

These coupon holders are used with High Pressure Access Systems (HPTM or MHTM) where pressure ratings up to 3,600 psi are required.

See HC Series Coupon Holders for more information.
