At Allendorph Specialties, we supply top-quality hammer unions engineered for rapid, reliable connections in oil, gas and chemical flowline systems. These precision-forged three-piece unions deliver metal-to-metal or elastomer-enhanced seals and are built to handle extreme pressures—from medium-duty manifold service to 15,000 psi and above. With ACME threads, quick make-up/break-out mechanics and full traceability to ASTM/AISI standards, our hammer unions are perfect for mud-pumping, cementing, kill-lines and sour-gas operations under NACE International MR-01-75 compliance. Choose Allendorph’s hammer unions for durable, interchangeable connections that safeguard performance — even in the toughest high-pressure, high-temperature or corrosive service environments.
