HSS Hand Tap Set - NPT / NPTF Thread
- • Material: HSS
- • Grade: M-2
- • Thread Type: NPT / NPTF
- • Standard Compliance: ANSI B1.20.1
Achieve leak-proof tapered pipe threads with our HSS Hand Tap Set in NPT/NPTF (National Pipe Thread) configuration, engineered for pressure-tight joints in oil, gas, and hydraulic systems. Conforming to ANSI B1.20.1 standards, these taps create the characteristic 1-degree 47-minute taper that produces interference-fit connections when used with mating NPT fittings. Essential for pipeline fabrication, refinery maintenance, and industrial plumbing across the UAE.

NPT / NPTF Tapered Pipe Thread Hand Tap Sets for Pressure Applications
National Pipe Thread (NPT) is the US standard for tapered pipe threads, designed to create pressure-tight seals through mechanical interference between male and female threads. Our HSS hand tap sets in NPT/NPTF configuration are manufactured to ANSI B1.20.1 specifications, featuring a precise 1-degree 47-minute taper that ensures leak-free joints without requiring additional sealants when properly assembled.
NPTF (Dryseal) variants offer an even tighter seal by controlling thread crest and root dimensions, making them ideal for high-pressure hydraulic, pneumatic, and fuel systems. These taps are indispensable in oil and gas pipeline construction, refinery maintenance, chemical processing plants, and fire protection systems. Maintenance teams in Dubai's industrial and energy sectors trust our NPT tap sets for reliable, repeatable pipe threading in carbon steel, stainless steel, and ductile iron.
