About The Product
What Is the WIKA Model 213.53 Pressure Gauge?
The WIKA Model 213.53 is a liquid-filled Bourdon tube mechanical pressure gauge engineered specifically for measuring locations subject to high dynamic pressure loads, vibration, pulsation, and shock. Its construction combines a corrosion-resistant stainless steel case with copper alloy (brass) wetted parts — a time-proven combination delivering robust performance in hydraulics, compressors, marine systems, and industrial machinery.
The gauge is manufactured and qualified by WIKA (Germany) to EN 837-1 and ASME B40.100 international standards. Its liquid case filling — glycerine, glycerine-water mixture, or silicone oil — efficiently damps the pressure element and movement, preventing needle oscillation and mechanical wear in high-cycle or vibrating environments. This makes the 213.53 one of the most widely specified compact liquid-filled gauges globally.
A key differentiator is its DNV GL type approval for the shipbuilding industry — qualifying it for use on ships, offshore platforms, and naval vessels. It also carries CE, UKCA, and CRN (Canada) approvals, making it suitable for global project procurement across regulated industries.
Working Principle: Bourdon tube deformation under pressure → mechanical pointer movement → dial reading

Material Options
Construction Materials & Case Filling Options
The WIKA 213.53 balances corrosion-resistant stainless steel case protection with cost-effective copper alloy wetted parts — the ideal combination for vibration-intensive applications involving non-corrosive media.
SS Case (Natural Finish)
Full stainless steel outer case with crimp ring — corrosion-resistant to industrial atmospheres, salt spray, and outdoor environments. Natural finish. IP65 sealed as standard; IP66 for ≥20 bar ranges.
Copper Alloy Bourdon Tube & Connection
Copper alloy (brass) for the Bourdon tube (up to 400/600 bar depending on NS) and process connection. Excellent compatibility with non-corrosive gaseous and liquid media, water, oil, compressed air, and hydraulic fluids.
Stainless Steel 316L Bourdon Tube
Automatically specified for NS 50 >600 bar and NS 63/100 >400 bar ranges — stainless steel 316L replaces copper alloy at high pressures, providing superior strength and fatigue resistance for demanding high-pressure cycles.
Glycerine Case Filling
Standard fill for vibration and pulsation damping. Medium temperature range: ambient –20 to +60°C, process –20 to +100°C. Compatible with most industrial process media. Glycerine-water mixture used for low-pressure ranges ≤2.5 bar.
Silicone Oil Case Filling
Extended temperature range: ambient –40 to +60°C, process –40 to +100°C. Preferred for outdoor installations, cold climates, marine service, and any application where glycerine could freeze or degrade. Inert and long-lasting.
C-Type or Helical Bourdon Tube
C-type (standard curved tube) for most pressure ranges. Helical Bourdon tube for very high-pressure ranges — provides greater movement angle for better accuracy and readability at elevated pressure levels.

FAQ
Frequently Asked Questions
Common questions about the WIKA 213.53 pressure gauge and how to source it from Zebco Engineering in India.
The WIKA 213.53 is a liquid-filled Bourdon tube pressure gauge with a stainless steel case and copper alloy wetted parts. What makes it stand out is its combination of very good vibration and shock resistance (from liquid case filling), especially robust design, and DNV GL type approval for the shipbuilding industry — making it one of the few compact gauges qualified for marine and offshore use. It is certified to EN 837-1 and ASME B40.100 and is available in NS 50 [2"], 63 [2½"], and 100 [4"] with scale ranges up to 0–1000 bar / 0–15,000 psi.
The 213.53 uses copper alloy wetted parts (Bourdon tube and process connection) with a stainless steel case — making it cost-effective for non-corrosive media in high-vibration environments. It is liquid-filled as standard and holds DNV GL approval for marine use. The 232.50/233.50 uses all-stainless-steel construction (both case and wetted parts) — suited for corrosive media, oil & gas, chemical, and pharmaceutical applications. The 213.53 maxes at 1000 bar; the 232.50/233.50 goes to 1600 bar. For media that attack copper alloys (acids, ammonia, acetylene), the 232.50/233.50 is required.
The WIKA 213.53 is available in bar (0–0.6 to 0–1000), psi (0–10 to 0–15,000), kPa (0–60 to 0–100,000), MPa (0–0.06 to 0–100), and kg/cm² (0–0.6 to 0–1000). Vacuum and compound ranges in all units are available (e.g. –1 to +40 bar; –30 inHg to +300 psi). Special scales include refrigerant temperature dials for NH₃ (R717) and other refrigerants. Dual scales and custom dials with red marks, circular arcs, or customer-specific graduation are available on request.
Yes — the WIKA 213.53 holds DNV GL type approval for ships, shipbuilding, and offshore applications, making it internationally recognized by classification societies. It is also CE certified (PED), UKCA approved (UK PES Regulations), and CRN registered for Canada. This broad approval base makes it the standard choice for shipyards, marine OEMs, and offshore EPC contractors procuring from India or internationally.
NS 50 [2"] and NS 63 [2½"] achieve EN 837-1 Class 1.6 (ASME B40.100 grade A). NS 100 [4"] achieves the higher EN 837-1 Class 1.0 (ASME B40.100 grade 1A — ±1% of measuring span). Temperature error for all sizes is ≤±0.4% per 10°C deviation from +20°C reference. Choose NS 100 when tighter accuracy, larger dial readability, or higher pressure ratings (max steady pressure = full scale for NS 100 vs ¾ scale for NS 50/63) are required.
Yes — NPT connections are fully available. The 213.53 is offered with process connections per EN 837-1 (G⅛B, G¼B, G½B, M12×1.5, M20×1.5), ISO 7 (R¼, R½), and ANSI/B1.20.1 (¼ NPT, ½ NPT). An optional copper alloy restrictor (Ø0.5 mm or Ø0.3 mm) can be fitted for additional damping in high-pulsation lines. Other connection threads (metric, PF, PT, UNF, flared, G, R) available on request.
