PTFE Lined 45 Degree Elbow
PTFE Lined 45 Degree Elbow Manufacturer
Mayur (Valves) System Private Limited, an ISO 9001:2015-certified company, has been a trusted PTFE Lined 45 Degree Elbow manufacturer and exporter since 1978. We supply engineered piping components for demanding industrial applications and export to 40+ countries worldwide. Our commitment to consistent quality, timely delivery, and a smooth customer experience has helped us serve clients across Europe, North America, the Middle East, Southeast Asia, Russia, and other international markets.
Our PTFE Lined 45° Elbow is designed for highly corrosive and high-purity fluid transfer systems where a smooth 45-degree directional change is required. Each elbow features a seamless virgin PTFE or PFA liner housed within a ductile iron or carbon steel body, providing excellent chemical and corrosion resistance. The robust construction supports long service life, dependable performance, and reduced maintenance requirements. These elbows are suitable for applications involving aggressive chemicals, solvents, and high-purity process media where reliable flow management and material compatibility are essential.
Offered in sizes from ½″ to 24″ (DN 15–600), these elbows meet ANSI Class 150/300 and PN 10–25 standards and are vacuum-rated, making them suitable for both pressure and vacuum service. The product complies with global quality standards such as ASTM F1545, ASME B16.9, and ISO specifications.
MVS PTFE Lined 45 Degree Elbow is manufactured via casting up to 150 mm and fabricated for larger sizes. The internal lining is available in FEP, PFA, and PVDF, providing high resistance to permeation and long-lasting performance. The design also includes flat-faced flanges, ideal for bolted flange connections.

What is a PTFE lined 45° elbow and where is it used?
A long radius 45° bend, lined with PTFE extruded to ASTM F1545-97. It is used wherever a line has to change direction by less than a right angle — offsets around equipment, staged changes of level, and sloped runs into and out of tanks. Two 45° bends produce a gentler offset than one 90° and cost less pressure drop, which is why they are preferred on pump suction and long transfer runs.
Which body, flange and lining materials are available?
Body in ASTM A234 Gr. WPB, IS 2062, Ductile Iron GGG40.3, ASTM A395 or Cast Steel ASTM A216 Gr. WCB. Flanges from IS 2062 plate, ASTM A105, CF8 (SS 304) or CF8M (SS 316). Lining in PTFE to ASTM F1545-97, or FEP, PFA, PVDF, ETFE, PP or HDPE, at a minimum 3.5 mm, 6.0 mm overall (±1.0 mm tolerance). Flange standards DIN PN10/16, BS 10, ASME 150/300 or mixed.
What sizes and test standards apply?
25 mm to 200 mm at 45° long radius, with other angles on request. Every elbow is spark tested at 20 KVDC and hydraulically tested at 29 kg/cm². Optional add-ons include rotating flanges, jacketed bends, earthing studs or lugs and vent extensions.
When should I use two 45° elbows instead of one 90°?
Where you are offsetting a line rather than genuinely turning a corner, and where pressure drop matters. Two 45° bends give a longer, gentler path than a single right angle, which lowers turbulence and erosion at the outside of the turn — the point where a liner wears first. On abrasive or high-velocity duty that difference translates directly into service life.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS manufactures at its own works — since 1978, ISO 9001:2015 certified — and exports across several continents. The minimum order quantity is 20 pieces. Non-standard angles, jacketed bends, rotating flanges, earthing studs and vent extensions are built to order.
