Description
NPT Galvanized Male Female Threaded Union 341 Pipe Fittings
When you need reliable, detachable connections in your piping system, NPT Galvanized Male Female Threaded Union 341 Pipe Fittings provide the perfect solution. These specialized high-integrity connectors are outlined for liquid transport frameworks requiring inflexible joining with dismantling capabilities. The '341' assignment particularly recognizes a funnel shaped situate union highlighting a Male-to-Female association arrangement. This plan dispenses with the require for extra pipe areolas amid establishment, decreasing strung joints and bringing down spillage dangers in your complex channeling projects.
You'll discover these fittings fathom basic support challenges by permitting you to disengage particular pipe areas or evacuate valves without cutting channels or pivoting whole frameworks. Made from premium moldable press with hot-dip galvanized coating, they convey uncommon solidness and erosion resistance for your mechanical applications.
Technical Specifications

Key Features
Superior Sealing Technology
The precision-machined metal-to-metal cone shaped situate gives leak-proof execution without perishable elastic gaskets. This plan permits rehashed dismantling without seal degradation.
Enhanced Durability
Hot-dip galvanization gives cathodic security against oxidation and stickiness, guaranteeing long-lasting execution in challenging environments.
Installation Efficiency
The male-female setup decreases establishment time by disposing of halfway areolas when interfacing to female ports.
Vibration Resistance
Malleable press development retains vibration and warm extension stresses, anticipating framework failures.

Materials and Surface Treatment
We fabricate these fittings from ASTM A197 pliable cast press, giving predominant ductility compared to dim press. This guarantees your fittings will distort or maybe than split beneath push. The hot-dip galvanization prepare applies a zinc coating surpassing 70 microns thickness, assembly ASTM A153 guidelines for greatest erosion protection.






Application Areas
These NPT Galvanized Male Female Threaded Union 341 Pipe Fittings are ideal for:
- Industrial water systems
- Gas distribution networks
- Steam applications
- Fire protection systems
- HVAC installations
- Process piping
- Chemical processing plants
- Oil and gas facilities






Installation Instructions
- Clean all string surfaces completely some time recently installation
- Apply suitable string sealant to NPT strings only
- Keep the inside funnel shaped situate clean and free of tape or paste
- Hand-tighten the union, at that point utilize torques to total connection
- Do not over-tighten as this may harm the funnel shaped seat
Packaging and Shipping
Your fittings arrive carefully bundled to anticipate harm amid transport. We utilize defensive materials and legitimate labeling for simple distinguishing proof. Standard bundling incorporates cardboard boxes with froth embeds for littler sizes and wooden cartons for bulk orders.





Quality Control
We execute rigid quality control conventions counting string gaging with calibrated L1 ring and plug gages, hydrostatic testing at 85 PSI, and galvanization adherence confirmation through copper sulfate testing. Each group experiences fabric spectroscopy to guarantee legitimate flexible press composition.






OEM and Customization Services
Our experienced group can customize fittings to meet your particular necessities. We offer different sizes, weight appraisals, and extraordinary coatings based on your application needs.






Frequently Asked Questions
Q: What's the difference between Figure 340 and 341 unions?
A: Figure 340 features Female/Female connections, while Figure 341 offers Male/Female configuration, eliminating the need for intermediate nipples.
Q: Do I need thread sealant?
A: Apply thread sealant only to the NPT threads. Keep the internal conical seat clean for proper sealing.
Q: What's the maximum operating temperature?
A: These fittings handle temperatures up to 350°F (176°C), though thread sealant may be the limiting factor.
