Pressure gauges with a 1/2" NPT process connection for larger ports and higher-flow hydraulic and process lines. Twin Hydraulics Engineering, Malaysia, stocks 1/2 NPT gauges in multiple dial sizes and pressure ranges.
1/2" NPT is the tapered-thread connection most common on American-standard equipment and on larger process and hydraulic installations; it is the usual fit for NS100 and NS160 gauges. NPT threads seal on the taper with PTFE tape or sealant, so they should not be interchanged with parallel BSP threads even though the nominal sizes look similar — a mismatch will leak or damage the port.
This range covers WIKA Bourdon-tube gauges with a 1/2 NPT lower (bottom) or back connection, dry or glycerine-filled, in brass, stainless-steel or safety-pattern cases, and in ranges from vacuum to high-pressure hydraulic.
What we need to quote: pressure range and units, dial size, connection position, case material, dry or filled, and the WIKA model number if known. Send the full type code from the nameplate if you have it — that avoids guesswork and gets you a firm price and lead time faster.
