Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems
The 90 degree elbow union connected is engineered for superior performance in hygienic fluid handling systems.
Why Engineers Specify This Item
- Precision-machined to comply with AS, BS, 3A, SMS, and DIN standards, this fitting meets stringent FDA, 3A, and CE certifications.
- Ideal for pharmaceutical and food processing industries, its smooth internal surface prevents bacterial buildup while maintaining optimal flow efficiency.
- Constructed from premium 304 or 316L stainless steel, it ensures exceptional corrosion resistance and durability.
- The tri-clamp connection design allows for quick assembly and disassembly, minimizing downtime during maintenance.
What It Prevents
- Tight radius bends that shear delicate product and erode on abrasive slurries
- Mitred elbows welded on site with internal beads that hold soil
- Return bends improvised from two 90s and a straight tube

How It Compares
Compared with Sanitary Tees
Specify the Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems where the duty is what this category is built for: 45, 90 and 180 degree bends in clamped, welded and threaded versions, including long radius bends for pumped product. Move to sanitary tees instead where the requirement is branch fittings in clamped, welded and union versions, including short outlet, Y-type, U-type and instrument tees.
Compared with Sanitary Reducers
Specify the Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems where the duty is what this category is built for: 45, 90 and 180 degree bends in clamped, welded and threaded versions, including long radius bends for pumped product. Move to sanitary reducers instead where the requirement is concentric and eccentric reducers that change line size without creating a pocket the line cannot drain.
Compared with A general industrial equivalent
An industrial-grade part of the same nominal size is usually cheaper and carries no declared hygienic surface finish, no crevice-free joint geometry and no material certificate. On a product contact line that difference shows up at the first swab test, not on the purchase order.
Installing and Living With It
Bring the two ferrule faces square before closing the clamp. Fit the gasket dry and seated in the groove, then tighten the clamp evenly; overtightening extrudes the gasket into the bore.
Purge the bore with inert gas before welding and keep heat input low so the heat affected zone does not discolour. Polish the internal weld to the finish specified for the rest of the line.
Do not use tape or sealant on a hygienic union thread. The seal is made by the gasket at the liner seat, not by the thread, so check the gasket is seated before tightening the nut.
Align the flange faces parallel before drawing the bolts up, and tighten opposite pairs in stages so the gasket is loaded evenly across the face.
Keep the duty inside the stated working temperature range of -20 C to 120 C. Running a CIP cycle hotter than the seal material allows is the most common cause of early failure on this item.
Do not exceed the 0-20Bar working pressure. Where the line sees pressure pulsation, specify a heavy duty or bolted clamp at the joints either side.
Record the standard, size, material and seal material fitted, so the replacement ordered in two years matches what is installed today.

Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems FAQ
What we are asked before this item is ordered.
What sizes is the Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems available in
The catalogue range is 1"-6". Dimensions follow the AS, BS, 3A, DIN, SMS, ISO standards. Confirm the tube outside diameter and wall thickness you work to when you enquire and we will match the exact dimensions before production.
Which material should I specify for the Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems
Material options are SS 304 or SS 316L. Choose 316L where chlorides are present or where the item will be welded into a line that has to be validated; 304 is adequate for neutral product and standard caustic CIP. Material certificates to EN 10204 3.1 are available on request.
Which seal material suits my cleaning cycle
The Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems is supplied with EPDM/SILICON/PTFE/VITON sealing options. EPDM is the default for hot water and caustic CIP, silicone for high temperature steam contact, PTFE for aggressive chemicals and Viton for oils and fats. Tell us the media and the peak CIP temperature and we will specify it on the order.
What is the lead time and minimum order for this item
Standard catalogue items such as the Sanitary Stainless Steel 90 Degree Elbow Union Connected for Food Processing Systems are typically 7-15 days, and small quantity orders of standard items are accepted. Custom sizes, special connections and bulk quantities are quoted with a confirmed date before production starts.
