OPERATING PRINCIPLE
How Cross Works
1. **Four-Way Internal Thread Design**: Features four internally threaded ports arranged in a cross configuration, suitable for intersecting piping layouts and for distributing or converging fluid flow in four directions.
-
2. **Precision-Cast Construction**
Built with robust wall thickness and a dense, uniform metallurgical structure—free from porosity or sand holes—ensuring stable and reliable pressure-bearing capacity.
-
3. **AISI 304 Stainless Steel**
Offers excellent rust and corrosion resistance, making it suitable for use with fresh water, mildly corrosive media, and outdoor installations.
-
4. **Precision-Machined Internal Threads**
Available with NPT, BSPT, or BSPP thread specifications; thread tolerances comply with ISO 7-1, DIN 2999, or ANSI B1.20.1 standards, ensuring a tight, leak-free assembly.
-
5. **150LB Pressure Rating**
Complies with the ISO 4144 standard, suitable for general industrial piping systems.
-
6. **Pickled and Passivated Surface Finish**
Provides a uniform metal surface that further enhances corrosion resistance; supports custom marking or engraving on the fitting body.
-
7. **Comprehensive Size Range**
Available in sizes from 1/4″ to 4″ (DN6 to DN100), with support for OEM branding and customization.

Frequently Asked Questions
Find answers to common questions about sizing, materials, threaded connections and operating conditions.
1、## What is Female Cross (4-Way Female Thread Cross)?
Female Cross is a cross-shaped pipe fitting with **four female internal threaded ports (F×F×F×F)** at 90° to each other. It allows fluid flow to be split or combined into four directions in a pipeline system. All four ports accept male threaded pipe nipples or fittings.
> Note: Differentiate from tee fittings (3-way only). Cross provides four connection points for piping.
2、 What is the difference between Cross and Tee fitting?
– Cross: 4-way connection (cross shape), 4 ports, flow can go to 4 directions.
– Tee: 3-way connection (T shape), only 3 ports, flow splits into 3 directions.
3、 What thread standards are available?
NPT (ANSI B1.20.1), BSPT / BSPP (ISO7/1, BS EN 10226). Metric thread M available for custom order.
> Important reminder: NPT and BSPT are not fully interchangeable. Wrong thread match will cause leakage. Please specify thread standard clearly on inquiry or PO.
4、 What materials can you supply?
– Stainless steel 304 / 316L (corrosion resistant, water, gas, chemical, instrument piping)
5、 What applications?
Water supply, compressed air, natural gas, fire protection, HVAC, instrument piping, oil, low & medium pressure industrial pipeline, plumbing systems.
6、What applications?
Water supply, compressed air, natural gas, fire protection, HVAC, instrument piping, oil, low & medium pressure industrial pipeline, plumbing systems.
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.
15、What should be done if the threads are found to be defective or do not meet requirements upon arrival?
Please provide photos, videos, and inspection records. We will assess the root cause; depending on the contractual terms, solutions may include product replacement, a partial refund, or a reshipment.”
