Round Steel Tube Connectors

Pneumatic and hydraulic systems are most afraid of fitting leakage. Hayi Technology's round steel tube connectors include ferrule type, flared type, push-in type, and tapered thread type. Materials are brass, stainless steel (304/316L), and engineering plastic. For example, a hydraulic equipment factory had fittings that seeped oil under high pressure. We provided stainless steel 316L ferrule type connectors. We tested them at 1.5 times the rated pressure for leaks. After assembly, the client ran the equipment for six months with no leaks. This case shows sealing reliability is the most important thing. Our MOQ is 1 piece.

Precision Threads and Seals – 100% Tested

We use high precision CNC lathes to machine the connector body. Threads are rolled or turned. Every thread is 100% inspected with go/no-go gauges. Seals are made of NBR, FKM, or PTFE to suit different media and temperatures. Every connector gets an air or hydraulic leak test at 1.5 times the rated pressure before shipping. We hold ISO9001:2015 certification. We provide material certificates. Our technicians can handle non-standard threads and non-standard sizes. Our round steel tube connectors can help your clients replace expensive imported brands like Parker or SMC.

Agents worry most about urgent client needs. Our common sizes of tube connectors are in stock and ship within 1 day. Custom sizes take about 15 days. Payment: 30% deposit, balance before shipment. Trade terms: EXW, FOB, DDP. Large orders get a discount. If any problem occurs, we talk immediately and improve after we find the cause. We have a dedicated after-sales person. Many clients used to buy from Parker or SMC at high prices. We offer OEM and ODM service with the same quality at 30-50% lower price. Our technicians can help you match thread standards and seal requirements. You can help your clients lower cost without losing quality.
