OPERATING PRINCIPLE
How Male Elbow Hose Nipple Works
1. **90° Combination Design**: Features a male threaded end and a hose barb (serrated) end, designed for a 90-degree connection between a threaded metal pipe and a flexible hose.
-
2. **Precision Casting Process**
Constructed with robust wall thickness and a dense, non-porous metallurgical structure, ensuring stable and reliable pressure-bearing performance.
-
3. **AISI 304 Stainless Steel**
Offers excellent rust and corrosion resistance; suitable for use with fresh water, mildly corrosive media, and outdoor installations.
-
4. **Precision-Machined Threads and Barbs**
Available with NPT, BSPT, or BSPP thread options. The hose barb features well-defined, smooth serrations that securely grip the hose, effectively preventing detachment or leakage.
-
5. **150LB Pressure Rating**
Compliant with the ISO 4144 standard, suitable for general industrial piping systems.
-
6. **Pickled and Passivated Finish**
Provides a uniform surface appearance and enhanced corrosion resistance; supports custom marking or engraving on the fitting body.
-
7. **Comprehensive Size Range**
Available in sizes from 3/8″ to 1-1/4″ (DN6 to DN100), with support for OEM branding/custom marking.

Frequently Asked Questions
Find answers to common questions about sizing, materials, threaded connections and operating conditions.
1、 What is a Male Elbow Hose Nipple?
It is a 90° elbow hose fitting, **one end is male pipe thread, the other end is hose barb (nipple shank)**. It connects rigid threaded pipe to flexible rubber / PVC hose, and changes flow direction by 90 degrees in one piece. The barb is inserted inside the hose and clamped with hose clamp for tight connection.
2、 What is the difference between Male Elbow Hose Nipple and Threaded Reducer Elbow?
Male Elbow Hose Nipple = **Male Thread × Hose Barb**, used to connect rigid pipe to flexible hose.
Threaded Reducer Elbow = **thread × thread**, both ends for rigid pipe connection, no barb for hose.
3、What stainless steel grades can you supply?
Standard grades:
– 304 / CF8 for water, air and general low-corrosion service
– 316 / 316L / CF8M for coastal, brine, chemical and chloride-containing media
4、What standards and pressure rating?
Cast version follows ISO4144 / MSS SP-114, Class 150LB (PN16).
Forged bar machined version complies with ASME B16.11, available in 3000LB / 6000LB.
Pressure rating depends on material, wall thickness and production process.
5、What materials can you supply?
– Stainless steel 304 / 316L (chemical, seawater, corrosive media)
6、How to specify size when placing inquiry?
Please provide **Male Thread Size + Hose Barb ID Size**.
Example: 1/2″ NPT Male × 12mm Barb, 3/4″ BSPT × 19mm Barb.
Barb can be single barb or multi-barbs for better hose grip.
7、Can you provide MTC material certificate?
Yes, EN10204 3.1 MTC with heat number is available. EN10204 3.2 third-party certificate can be arranged at buyer’s extra cost.
8、Surface finish options?
Standard: pickled matte finish.
9、Can you do laser marking?
Yes. We can mark size, grade, heat number, customer logo or brand on the flats.
10、Packaging for sea shipment?
Male threads are protected by plastic thread caps. Packed into export cartons, then loaded on fumigated wooden pallets with waterproof stretch film to avoid scratch and thread damage.
11、What is the lead time?
Typically, shipments are dispatched within 7–15 days of receiving the deposit, depending on the order quantity.
12、How is quality controlled?
Raw material inspection → CNC machining → Thread inspection → Hydrostatic testing → Visual inspection → Final dimensional verification before packaging.
13、Which Incoterms are available for overseas buyers?
We offer FOB (Free On Board) terms, with the shipment originating from a Chinese port. We will provide a commercial invoice, packing list, and bill of lading for import customs clearance.
14、Which Incoterms are available for buyers?
We offer FOB (Free On Board) or CIF (Cost, Insurance, and Freight) terms, with shipments originating from a Chinese port. We will provide a commercial invoice, packing list, and bill of lading for customs clearance.
