PERFECT LOADING
PTFE-lined break-away couplings are engineered to safely transfer highly aggressive fluids—like acids, solvents, or caustic chemicals—while maintaining the same spill-preventing magic as their non-lined counterparts. The secret sauce? A PTFE (Polytetrafluoroethylene) lining, which is like a non-stick, chemical-proof coating inside the coupling. This lining ensures that even the nastiest fluids don’t eat away at the coupling or cause leaks.
So, why go for PTFE-lined break-away couplings over standard ones? It’s all about handling the extreme. These couplings are designed for scenarios where regular materials would fail—think hydrochloric acid, sodium hydroxide, or other corrosive nightmares. The PTFE lining provides unmatched chemical resistance, while the break-away mechanism ensures safety during unexpected incidents.
Plus, they offer the same benefits as standard break-away couplings—spill prevention, easy maintenance, and worker safety—but with the added durability needed for chemical-heavy industries. Whether you’re in pharmaceuticals, petrochemicals, or specialty chemical production, these couplings are your go-to for safe, reliable fluid transfer.
PTFE-lined break-away couplings have the same core mission as regular break-away couplings: prevent spills and protect equipment during unexpected pull-away incidents. But they’re tailored for the aggressive fluids. Here’s what they bring to the table:
Like standard break-away couplings, they snap apart under excessive force (e.g., a tanker pulling away), sealing both ends to prevent leaks. This is critical for hazardous chemicals where even a drop can be dangerous.
The PTFE lining acts as a barrier, shielding the coupling from corrosive fluids that would destroy standard metals or seals.
When the coupling separates, valves close instantly, ensuring near-zero leakage.
Handles a wide range of aggressive fluids, from sulfuric acid to chlorinated solvents, without degrading.
By preventing spills, these couplings protect workers from exposure and the environment from contamination.
The materials in PTFE-lined break-away couplings are chosen to withstand the harshest conditions. Here’s the breakdown:
Typically made of 316 stainless steel, which is already corrosion-resistant and strong enough for industrial use. Stainless steel is like the sturdy backbone of the coupling, holding everything together under pressure.
The star of the show, PTFE (often known by the brand name Teflon) is a fluoropolymer that’s virtually impervious to chemicals. It’s non-reactive, slick, and can handle extreme temperatures, making it perfect for lining the inner surfaces where fluids flow.
Usually made of stainless steel or other high-strength alloys, these are calibrated to snap at a specific force, allowing the coupling to separate safely.
In some designs, parts like flanges or adapters may use Hastelloy (specialty alloys) for even greater resistance to specific chemicals.
Seals are critical in any break-away coupling, but in PTFE-lined versions, they’re even more specialized to handle aggressive fluids. Here’s what you’ll typically find:
Many PTFE-lined couplings use PTFE itself as the primary seal material due to its unmatched chemical resistance. PTFE O-rings or gaskets ensure a tight, leak-free seal, even with fluids that would dissolve other materials.
PTFE-lined Main Seal (RIGHT)
Operating a PTFE-lined break-away coupling is as straightforward as its non-lined cousins, but with extra peace of mind for chemical applications. Here’s how it works:
The coupling is installed in-line, typically between a hose and a fixed point (like a loading arm) or between two hoses. It’s connected using NPT threads, flanges, or other fittings compatible with your system.
During regular fluid transfer, the coupling allows smooth flow with minimal pressure drop. The PTFE lining ensures the fluid doesn’t react with or corrode the coupling’s interior.
If excessive force is applied (e.g., a tanker drives off), the break bolts or shear pins snap, and the coupling separates into two halves. Internal valves (often poppet or flip-flap designs) close instantly, sealing both ends to prevent leaks.
After a break, the coupling can often be reassembled on-site with a spares kit (new break bolts or pins).
