application
- Quick connection of grooved main pipes to internal thread fire hydrants/valves in fire protection systems;
- connection of HVAC pipes to internal thread radiators or pump bodies;
- replacement of damaged external thread connections during industrial equipment maintenance;
- situations where grooved pipes need to be connected to internal thread containers (such as water tanks).
advantages
1. Fast interface conversion: Direct connection (single-piece integrated groove-end clamp/connection, external thread ends in accordance with NPT standards, BSPT threads) directly to internally threaded equipment, without the need for an adapter.
2. Quick installed convenient and time-saving: groove-end clamps can be locked in seconds, threaded ends can be manually tightened, 60% installation labor saving.
3. Strong and durable：Dedicated ductile iron design, strong anti-pressure strength and no cracking.Ductile Iron body with hot-dip galvanized or red paint coated to prevent rusting last more than 15 years in service.
4. High pressure safety test: Internationally standard UL/FM testing and passed, no leakage at 300-500 psi.
5. Compatible worldwide: Supports NPT and BSPT thread specifications — fits on the equipment interfaces of America, Europe and Asia
packing
- Individual items are protected with a rust-proof oil coating wrapped in bubble wrap to prevent scratches during transportation and rusting due to moisture.
- Standard packaging consists of high-strength corrugated cardboard boxes with EPE foam inserts to secure the product. The box includes a product label (with dimensions and thread type), a certificate of conformity, and a warranty card.
- The outer box is clearly printed with: product name, specifications (e.g., 1-1/2“ NPT), quantity, gross weight/net weight, UL/FM certification marks, and marked with ”↑Upward“ and ”Moisture-proof” icons.
- All packaging meets the ISTA 3E export transportation testing standards.
