Answers to common questions about Masofit hydraulic fittings, ISO 8434-1 / DIN 2353 standards, materials, pressure series, OEM supply, and ordering.
What products does Masofit manufacture?
Masofit manufactures precision hydraulic fittings and accessories — including ISO 8434-1 / DIN 2353 24° metric tube fittings, JIC 37° flare connectors, BSPP / BSPT / NPT adapters, seamless steel tubes, tube clamps, hose fittings, seals, valves, and related accessories for industrial fluid power systems.
What is the Masofit Hydraulic Fittings Catalogue?
The Masofit Hydraulic Fittings Catalogue is our official product reference covering metric tube fittings, flare connectors, adapters, tubes, clamps, hose fittings, and valves. You can browse it online under Downloads / Catalogue or download the PDF for part numbers, dimensions, and pressure data.
Which standards do Masofit fittings comply with?
Our fittings are manufactured to relevant international standards including ISO 8434-1 and DIN 2353 for 24° metric tube ends, SAE J514 for 37° flare (JIC), ISO 1179-2 / ISO 228-1 for BSPP ports, BSPT taper threads, and ASME B1.20.1 for NPT. Production operates under an ISO 9001:2015 quality system.
What is the difference between LL, L, and S series?
These are pressure series for 24° compression fittings. LL (very light) suits lower-pressure lines, L (light) covers general industrial hydraulics, and S (heavy) is for higher working pressures — up to around 800 bar depending on tube O.D. Always select the series that matches your system working pressure and tube size.
What materials are available for Masofit fittings?
Standard options are carbon steel, stainless steel 304, stainless steel 316, and brass. Carbon steel is typically supplied with Cr(VI)-free zinc plating; zinc-nickel and stainless passivation are available on request for corrosive or marine environments.
What surface finishes do you offer?
Carbon steel fittings are normally finished with Cr(VI)-free zinc plating. Optional zinc-nickel plating and stainless steel passivation are available. Tell us your corrosion, salt-spray, or customer specification requirements when requesting a quote.
What pressure ratings do Masofit hydraulic fittings support?
Working pressure depends on fitting type, series (LL / L / S), tube O.D., and material. Light and heavy series metric fittings can reach several hundred bar — with S-series options up to about 800 bar on smaller sizes. Always verify the catalogue rating for your exact part number against system design pressure.
How do Masofit part numbers work?
Masofit uses MAS / MF coding for catalogue items. Part numbers typically encode size (tube O.D.), series (LL / L / S), and configuration. Full coding rules, dimension tables, and examples are published in the Masofit Hydraulic Fittings Catalogue and on each product page.
Do fittings carry product marking and batch traceability?
Yes. Fittings are marked MAS / MF with material grade and batch identification where applicable, supporting batch traceability from production through dispatch for OEM and quality documentation requirements.
Are fittings pressure tested before dispatch?
Yes. Critical fittings and assemblies follow hydrostatic / high-pressure test routines as part of our quality process. Test documentation can be provided with shipments when specified on the order or quality plan.
What tube sizes do you cover?
Metric tube fittings commonly cover tube outer diameters from about 4 mm up to 42 mm, depending on series and configuration. Imperial / flare sizes follow SAE J514 ranges. Confirm exact availability in the catalogue dimension tables or with sales.
Do you supply nut and ferrule (cutting ring) sets?
Yes. Tube connector parts such as nuts and profile rings (cutting / bite rings) are available as catalogue items for ISO 8434-1 metric tube ends, along with complete union, elbow, tee, and stud configurations.
What thread forms are available on stud connectors and adapters?
We supply BSPP (parallel with seal), BSPT (taper), NPT, and metric port threads on studs and adapters, plus 24° tube ends and 37° flare ends as listed in the catalogue. Never mix incompatible thread standards on the same connection.
Do you offer JIC 37° flare fittings?
Yes. Masofit’s range includes 37° flare unions, elbows, and tees aligned with SAE J514 practice for systems that specify JIC flare connections alongside metric tube and BSP / NPT adapters.
Do you supply seamless steel tubes and tube clamps?
Yes. Seamless steel hydraulic tubes (multiple O.D. ranges) and light / heavy series tube clamps are part of the catalogue range, supporting complete line installation from tube to fitting to support.
Are hose adapters and hose assemblies available?
Yes. The catalogue includes hose adapters (e.g. BSPP 60°), hose elbows / tees, hose pipe spares, and complete hose assemblies. Share hose size, end fittings, length, and working pressure for assembly quotes.
Do you sell seals, O-rings, and bonded washers?
Yes. Accessories include NBR O-rings, copper washers, bonded seals, elastomeric seals, and related sealing rings used with port studs and adapters. FKM (Viton) options can be discussed for higher temperature or chemical duty.
Which industries use Masofit fittings?
Typical applications include construction & earthmoving, industrial machinery, machine tools, injection & blow moulding, steel & rolling mills, oil & gas, agriculture, automotive manufacturing, chemical plants, and marine & shipbuilding hydraulics.
Where is Masofit based?
Masofit is a brand of Naadnia Group, with manufacturing based in Jaipur, Rajasthan, India (Jagatpura, 302033). We supply OEMs, distributors, and industrial buyers in India and export markets.
How do I request a quote?
Use the Contact page form, email sales@masofit.com, or call / WhatsApp +91 8852045107. Include part numbers or drawings, material, quantity, delivery location, and any OEM marking or packaging requirements for a faster quotation.
What information should I include in an RFQ?
Share tube O.D. / thread size, series (LL / L / S) or pressure rating, material and finish, quantity, required standards, destination, and target lead time. For custom parts, attach drawings (PDF / STEP) and any customer specification or PPAP needs.
Are custom and OEM fittings available?
Yes. Masofit supports OEM branding, special configurations, and custom-engineered connection solutions. Visit Custom & OEM or contact engineering@masofit.com with drawings and annual volume estimates.
Can you supply private-label / OEM branding?
Yes. OEM marking, custom packaging, and labelling programmes can be arranged for qualified volumes. Discuss brand guidelines and quality documentation requirements with our partners or sales team early in the enquiry.
What are typical lead times?
Catalogue items are typically quoted with lead times around 2–4 weeks depending on stock, material, and quantity. Custom / OEM programmes may need longer for tooling, samples, and approval. Confirm current lead time on each quotation.
Do you ship internationally?
Yes. Masofit ships domestically across India and internationally via freight forwarders and courier partners. Export packing, documentation, and Incoterms are agreed on the order confirmation.
How should 24° compression fittings be installed?
Cut tube square, deburr, clean thoroughly, assemble nut and cutting ring correctly, and tighten to Masofit torque / turn guidance for the size and series. Support the tube near the fitting, avoid mixing thread standards, and re-check after first pressurisation.
Do you provide a ferrule pre-assembly (biting) machine?
Yes. A pre-assembly machine for ferrule biting is listed in the Masofit catalogue for workshops that need consistent ring bite before final installation on the machine or vehicle.
How do I choose between carbon steel and stainless steel?
Use carbon steel (plated) for general industrial hydraulics. Choose SS304 / SS316 for corrosive media, washdown, outdoor, or marine environments. Confirm pressure derating and seal compatibility with your fluid and temperature.
