Description
The National Oilwell Varco (NOV) Shaffer Sentinel II BOP Ram Packer is a critical sealing component designed for ram-type blowout preventers in oil and gas drilling operations. This model, OEM# 722189, is specifically configured for 7-1/4" bore size with a 5,000 psi (5M) pressure rating, optimized for sealing around 2-7/8" tubing. Made from durable NBR (nitrile butadiene rubber) material, it provides reliable well control by preventing blowouts during drilling, workover, or completion activities. Key features include fixed pipe ram design for precise sealing on specific tubing sizes, high resistance to hydrocarbons and drilling fluids, and compatibility with Shaffer Sentinel II BOP systems. Advantages over similar products include NOV's robust engineering for extended service life, ease of installation, and compliance with API standards (API ID 119.4). Benefits include enhanced safety, reduced downtime, and cost-effective maintenance. Drawbacks may include limited flexibility for variable bore applications compared to VBR packers and expiration dates affecting shelf life (this unit expired 03/20 but remains unused). Ideal for onshore/offshore rigs requiring dependable pressure control. This unused unit offers new-condition performance at surplus pricing.
