Frequently Asked Questions (FAQ)

What is the difference between JIC and SAE ORB 3/8 inch fittings?

JIC 37° flare fittings use a metal-to-metal seal created by the contact of two 37-degree flared surfaces. SAE O-ring Boss (ORB) fittings use a straight thread and seal via an O-ring compressed into a boss. ORB fittings often provide a more reliable seal in high-vibration applications and are reusable with a new O-ring.

Are your 3/8 inch hydraulic fittings compatible with metric tubing?

Yes. We offer specific adapters and metric parallel thread (DIN / ISO) fittings in the 3/8 inch size range to bridge between imperial and metric system components. It is crucial to specify the exact thread and connection types you need to ensure compatibility.

What pressure can your standard carbon steel 3/8 inch JIC fitting handle?

Our standard carbon steel 3/8 inch JIC flare fittings are typically rated for working pressures up to 6,000 PSI. The exact rating can vary based on the specific fitting configuration (e.g., straight vs. elbow). Always consult the technical datasheet for the precise product.

Do you offer certifications for your fittings?

Yes. We can provide material certifications (e.g., Mill Certificates) and our fittings are manufactured to comply with relevant SAE, JIC, and ISO standards. Specific industry certifications (e.g., for marine or offshore use) can be discussed based on project requirements.

What is your minimum order quantity (MOQ) for these fittings?

We offer flexible MOQs to cater to both large OEM projects and smaller MRO needs. Please contact our sales team with your specific requirements for a tailored quotation and to discuss volume pricing advantages.
