Key Features
Serviceable Union Design
The three-piece union assembly separates cleanly at the elbow joint without requiring pipe movement. This reduces maintenance downtime in installations where access is restricted or where frequent line inspection is required.
Flat Seal Gasket Options
PTFE gaskets provide chemical resistance and low friction across a wide temperature range, making them the standard choice for aggressive media. EPDM suits steam and hot water service. Conical seal configuration is available where higher seating load is required for specific pressure conditions.
Dual Material Grade
SS304 covers the majority of general industrial applications. SS316 adds molybdenum content for superior resistance to chloride-containing media and marine environments, meeting the material requirements of pharmaceutical, food processing, and offshore installations.
Octagonal Nut Profile
The octagon polygon profile on the union nut provides flat surfaces for standard wrench engagement across all sizes, supporting consistent torque application and reducing the risk of connection damage during installation.
Application Scenarios
Chemical Processing
PTFE gasket compatibility makes this union elbow connector suitable for acid, alkali, and solvent transfer lines where elastomeric seals would degrade. The union structure supports scheduled line flushing and seal replacement without pipe cutting.
Food & Beverage Production
SS316 body with PTFE or EPDM gaskets meets material requirements for contact with food-grade media. The smooth bore union connection eliminates crevices at the joint face, reducing residue accumulation between cleaning cycles.
Pharmaceutical Manufacturing
Precision-machined sealing faces and traceable SS316 material support CIP/SIP-compatible installations. The detachable union structure allows joint inspection as part of routine validation procedures.
Industrial Fluid Systems
90-degree directional change in a compact union fitting reduces the component count in tight routing situations. Available in SS304 for cost-effective deployment across general water, air, and non-aggressive media lines.

Frequently Asked Questions
Q: Does this union elbow support high-temperature service?
A: Operating temperature range depends on the gasket material selected. PTFE handles a wider temperature range including cryogenic and elevated heat applications, while EPDM is preferred for steam service. Contact our team with your specific temperature requirements for confirmation.
Q: Can this fitting be used with both BSP and NPT threaded systems?
A: The union elbow is available in either BSP or NPT thread form. The two standards are not interchangeable - specify your required thread type at the time of inquiry to ensure compatibility with your existing pipeline.
Q: Is SS316 necessary for food or pharmaceutical applications?
A: SS316 is generally the preferred grade for food contact and pharmaceutical service due to its molybdenum content and superior corrosion resistance. However, material selection should also account for your cleaning agents, operating temperatures, and any applicable regulatory requirements in your market.
Q: Can the union nut be replaced independently without changing the full assembly?
A: The union structure allows individual components to be serviced. Replacement parts availability for specific sizes can be confirmed with our team prior to ordering.
Q: What is the lead time for standard and custom orders?
A: Lead time varies by size, material grade, and order volume. Submit your specification and quantity requirements for a confirmed lead time from our sales team.
