Unique-Bargains MPL4-03 90° Swivel Elbow 4mm x 3/8 NPT Pneumatic Accessory 3pcs

SKU CH-W4MC-6RBRX MPN MPL4-03

Three push-to-connect elbow fittings join 4 mm tubing to 3/8 NPT threads with a 90° swivel, rated to 1.5 MPa and −10 to 60 °C

  • Connects 4 mm tube to 3/8 NPT thread instantly
  • 90° swivel elbow adjusts angle without pipe stress
  • Rated 1.5 MPa pressure resistance for demanding air lines
  • Operates reliably from -10 °C to 60 °C
  • Pack includes three fittings for multi-point installations

Universal Pneumatic Fitting

The Unique-Bargains MPL4-03 is a 90 degree swivel elbow male connector designed for pneumatic air systems. It accepts 4mm outer diameter tubing on the push-to-connect end and features a 3/8 NPT male thread on the other. The pack contains three black and silver tone fittings made from plastic and metal. They suit maintenance engineers and hobbyists assembling compressed-air circuits.

Replaces Fixed Elbow Fittings

Swap out rigid 90 degree elbows when tube routing requires angular adjustment after installation. The swivel body rotates freely to align the tube angle, then locks in place without kinking the line. The upgrade is worth it on vibrating machinery or tight panels where a fixed elbow would stress the tubing or leak at the thread seal.

Sustained Pressure Performance

Rated for continuous operation from 0 to 1 MPa with a guaranteed pressure resistance of 1.5 MPa across a temperature span of -10 to 60 Celsius. The release cap withstands prolonged loads without tripping, while the composite body resists abrasion, crushing and corrosion. Leak-free sealing holds over extended duty cycles in industrial environments.

Questions about this item

What tube and thread sizes does the 90° swivel elbow accept?

The fitting connects 4mm OD tubing to a 3/8 NPT male thread.

What is the correct way to insert the tubing so it seals?

Cut the tube flat, push it fully into the fitting until it bottoms out, then pull back gently to lock the collet.

When should the fitting be replaced based on pressure limits?

Replace it if system pressure exceeds 1.5MPa or if leaks appear after repeated pressurisation cycles.
