            B1 Kits & Parts           

BST's B1 flow control chokes are easy to repair and replace trim and other parts without removing the choke body from the wellhead or flow line. 

All complete trim repair and resizing kits include a matched stem and seat, a PTFE packing stack to seal the stem to the bonnet, and the two Viton O-rings required to seal the bonnet to the body and the seat to the body.  You can calculate the liquid or gas flow for any trim size (or percentage thereof) at BST's flow calculator web pages.

All kits and parts offered on this page are rated for both standard (sweet) and H2S (sour) oil and gas service per NACE MR-01-75.  Viton O-rings are standard, with Aflas as a premium option.

All standard B1 parts and kits are in stock and available for immediately shipment, except as noted.  Contact BST Sales for price and delivery of these items.
