Fitting FAQs
What fitting standards do you manufacture to?
We manufacture fittings to NPT (National Pipe Thread), BSP (British Standard Pipe), metric thread, ISO 4401 (subplate cavity), and ORB (O-ring boss) standards. Most hydraulic and pneumatic systems use ISO 4401 metric threads or NPT. Instrumentation fittings follow NPT or SAE (Society of Automotive Engineers) standards. Specify your required thread form on your drawing, and we will machine accordingly.
What materials are best for high-pressure fittings?
Stainless steel 316 is the standard choice for high-pressure hydraulic and pneumatic fittings due to strength, corrosion resistance, and pressure rating. Steel 4140 (hardened) is used for extreme high-pressure (>3000 psi). Brass is used for low-pressure air, water, and gas applications. Titanium is selected for aerospace weight-critical applications. Specify your working pressure and environment, and we will recommend the optimal material.
Can you manufacture fittings with custom thread forms?
Yes. We can machine custom thread forms including conical (tapered), straight threads, modified buttress threads, and proprietary profiles. CNC threading is precise to ±0.05mm pitch. If you have a non-standard requirement, provide the thread profile or pitch, and we will machine it.
What is the typical lead time for custom fittings?
Lead time for custom fittings is 5–10 business days depending on quantity and complexity. Simple fittings (single thread, minimal features): 5–7 days. Complex fittings (swivel, multi-hole, integral seals): 7–10 days. High-volume orders (50+) have optimized timelines. Request a quote with your required delivery date.
Do you provide pressure testing for fittings?
Yes. We can arrange pressure testing of finished fittings at your specified test pressure (up to 5000 psi typical). Each fitting can be tested for leak-free performance before delivery. Test certificates and pressure ratings are provided. Specify your test pressure on your quote request.
Can you produce fittings for food-grade applications?
Yes. Food-grade fittings are manufactured from stainless steel 316 with certified material traceability. Passivation and cleaning to food-safety standards are available. We follow FDA compliance for food-contact surfaces. Specify "food-grade" on your quote request and we will ensure proper material handling and documentation.
