DEENPU ISA Annular BOP — Packing Elements
DEENPU ISA Spherical Annular Packing Elements are the heart of the annular BOP, providing the sealing capability on multiple pipe sizes, hexagonal kelly, and open hole. Available in four elastomer materials to match your well conditions:
- NR (Natural Rubber/Polyisoprene) — High tensile strength, resilience, abrasion resistance. Ideal for snubbing and general drilling. Temp range: -60F to 180F
- NBR (Nitrile/Buna-N) — Excellent oil and fuel resistance. Good for oil-based mud systems. Temp range: -30F to 250F
- HNBR (Hydrogenated Nitrile) — Superior H2S resistance, high temperature capability. Ideal for sour gas wells and deep drilling. Temp range: -30F to 350F
- FKM (Fluoroelastomer) — Maximum chemical resistance. For extreme H2S, CO2, and chemical injection environments. Temp range: 0F to 400F
