Pressure gauges with a 1/4" BSP (parallel) process connection — a widely used port thread across hydraulic and pneumatic equipment. Twin Hydraulics Engineering supplies 1/4 BSP gauges throughout Malaysia.
1/4" BSP (G 1/4, parallel thread) is the most common gauge connection in Malaysia and across European and Asian-built hydraulic and pneumatic equipment. It seals on a bonded washer or O-ring against the port face rather than on the thread, and is the standard fit for NS50 and NS63 gauges on power packs, valve stands, manifolds and test points. Do not substitute NPT tapered threads — the two are not compatible.
This range covers WIKA Bourdon-tube gauges with a G 1/4 bottom or back connection, dry or glycerine-filled, in brass, stainless-steel or safety-pattern cases, across vacuum, low-pressure and hydraulic ranges up to 1,000 bar.
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.
Twin Hydraulics Engineering supplies WIKA pressure gauges from stock in Shah Alam and Butterworth, Malaysia. Send us a photo of the existing gauge or contact us for stock and pricing.
