Product Benefits

Custom End Fittings

Custom End Fittings

No two engine or transmission ports are the same. Orscheln offers customized end fittings for use with a variety of tube materials, both metal, and polymers, to meet your specific needs.

Formed Metal Tubing

Formed Metal Tubing

With in-house tube bending capabilities, we can design and manufacture tubes of various sizes for simple and complex routings alike.

Customer-specific blade & markings

Customer-specific blade & markings

Customers can designate their desired blade type and markings. Our Twist2Lock system is manufactured with accuracy in mind. Dipsticks are calibrated to the tube when manufactured, so your fluid level measurement will be repeatable and dependable. Customers can also designate their desired blade type and markings.
