H2S Resistant Hammer Union Seals | FKM with Stainless Steel Backup Ring | 15,000 PSI CWP
Overview
In the high-stakes oil patch, standard sealing solutions often fall short when faced with the dual challenges of extreme heat and corrosive gases. Our Temperature Resistant FKM Lip Style Hammer Union Seals represent the pinnacle of sealing technology for HPHT (High Pressure High Temperature) and Sour Service** environments.
Key Features and Benefits
Extreme Thermal Stability: Specially formulated FKM (Fluoroelastomer) maintains its elastomeric sealing force at temperatures up to 446°F (230°C), where standard seals melt or fail.
Pressure-Energized Lip Profile: The "Lip Style" design uses the internal line pressure to flare the seal lips against the union sub, ensuring a tighter seal as pressure increases.
Total H2S & CO2 Immunity: Engineered for Sour Service, this FKM compound is resistant to chemical degradation, swelling, and cracking caused by high concentrations of Hydrogen Sulfide and Carbon Dioxide.
Corrosion-Proof SS Reinforcement: The integrated Stainless Steel backup ring is immune to sulfide stress cracking (SSC), providing a rigid anti-extrusion barrier that brass rings cannot offer in sour environments.
Zero-Leaking Integrity: Precision-molded to meet the tightest North American oilfield tolerances, ensuring a 100% gas-tight connection for high-pressure flowback and stimulation

Common Applications
Our FKM/SS seals are the "Gold Standard" for high-stakes oilfield servicing: Sour Gas Production: Critical sealing in wells with high H2S and CO2 concentrations.
Well Stimulation & Acidizing: Handling aggressive chemicals and acids that degrade standard Nitrile seals.
High-Pressure Fracturing: The go-to seal for discharge manifolds in "Iron" fleets operating in corrosive basins.
HPHT Well Testing: Providing safety and security during initial flowback and testing of deep, high-pressure wells.
FAQ
Q1: Why do I need "Temperature Resistant" FKM for Fig 1502 unions?
A: At 15,000 PSI, the friction and fluid dynamics in the flowline can generate significant heat. Our FKM seals stay resilient up to 446°F, ensuring safety during high-rate fracking or steam service.
Q2: How does the "Lip Style" profile improve sealing?
A: Unlike flat seals that rely on compression alone, the Lip Style is "pressure-energized." It uses the fluid pressure to force the seal's edges against the metal, creating a more dynamic and reliable gas-tight barrier.
Q3: Is FKM compatible with all fracking chemicals?
A: FKM is compatible with the vast majority of oilfield chemicals, including acids and aromatic hydrocarbons. For specific chemical compatibility charts, please contact our technical team.
Q4: What is the shelf life of these seals?
A: Our FKM seals have an exceptional shelf life of 20 years when stored correctly, compared to just 5-10 years for NBR. This makes them ideal for emergency stock and long-term inventory.
