Find out what the OD seal does and why quality matters when you’re replacing this valve part.
Why OD Seals Are Used
The OD Seal for BPVs and TWCVs is a crucial component of each. A back pressure valve or two-way check valve OD seal is used in the groove right above the OD threads to seal the valve to the inner diameter of the tubing hanger. Heshka Oil offers these seals in both Hydrogenated Nitrile Rubber (HNBR) or Viton (FKM) and can also be manufactured in AFLAS when required.
HNBR OD seals are the standard seal offered at Heshk Oil and fit many different environments. They have great resistance to oil and water based mud, crude oils, methane, carbon dioxide and are suitable for H2S environments.
Viton OD seals on the other hand have a wider operating temperature range and chemical resistance. Viton OD seals are also suitable when there is a higher presence of H2S.
In addition to the different materials offered, Heshka Oil offers these seals in different sizes for all our BPVs and TWCVs. These sizes range from 2” nominal to 6-5/16” nominal.
