FOH H1168X12MR-SS — 316 Stainless Steel Male Straight Stud Push-to-Connect Fitting, 12mm Tube, R3/8 Thread (BSPT)

The FOH H1168X12MR-SS is a 316 stainless steel male straight stud push-to-connect fitting with FKM seals. It connects pneumatic tubing directly into a compatible female-threaded machine or valve port. The listed connection is 12mm Tube, R3/8 Thread (BSPT).

The FOH range provides an additional sourcing option alongside the standard S-series stainless fittings. Compare tube outside diameter, thread form, sealing details and published ratings before substituting one series for another.

Why 316 Stainless Steel and FKM Matter

Grade 316 stainless steel contains molybdenum, which improves resistance to certain types of localized corrosion compared with grade 304. That is useful on food, beverage and pharmaceutical machinery where exposed pneumatic components may encounter moisture and repeated cleaning. It is not corrosion-proof: chloride-rich cleaners, crevices and high temperatures still require assessment. FKM fluoroelastomer seals are used at the tube connection. FKM can be suitable for many industrial services, but it is not universally compatible with hot sodium-hydroxide washdown, steam or every cleaning chemical. Check the actual fluid, concentration, temperature, exposure time and seal grade before specifying the fitting.

Key Features

  • Male Straight Stud configuration: Connects pneumatic tubing directly into a compatible female-threaded machine or valve port.
  • Specified connection: 12mm Tube, R3/8 Thread (BSPT). Match the tubing outside diameter and the applicable thread or stem style.
  • Grade 316 stainless steel body for improved resistance to many wet, cleaned or corrosive machinery environments.
  • FKM sealing elements at the tube interface; chemical, pressure and temperature compatibility must be confirmed.
  • Push-to-connect assembly reduces the need for separate tube nuts or compression ferrules.

Typical Applications

  • Compressed-air distribution on food and beverage packaging or filling equipment
  • Pneumatic actuators, valves and control circuits near frequently cleaned production equipment
  • External air or vacuum tubing on pharmaceutical manufacturing machinery, subject to equipment specifications
  • Connection or extension of pneumatic tube runs on industrial machines

How the Male Straight Stud Works

A male straight stud reduces the number of separate adapters between a valve port and tubing. Verify the exact thread form and sealing method; NPT, BSPP and BSPT connections require different mating arrangements. The FOH H1168X12MR-SS is specified with 12mm Tube, R3/8 Thread (BSPT).

Selection Guidance for Washdown and Pharmaceutical Equipment

These fittings are described for pneumatic or vacuum circuits on processing machinery, not as certified sanitary product-contact fittings. A direct food- or pharmaceutical-contact application requires separate confirmation of hygienic design, material compliance and the relevant approvals. For chemical washdown, assess the 316 metal body and FKM seal individually; in particular, do not assume hot caustic cleaners or chlorinated disinfectants are compatible.

Installation check: Cut approved tubing squarely, insert fully to the stop and check tube retention before pressurizing. Match all connection sizes and thread forms, and verify operating pressure, vacuum rating, temperature and cleaning chemistry against the product data.

Frequently Asked Questions

What does the FOH H1168X12MR-SS male straight stud do?

It connects pneumatic tubing directly into a compatible female-threaded machine or valve port. The specified connection is 12mm Tube, R3/8 Thread (BSPT). A male straight stud reduces the number of separate adapters between a valve port and tubing. Verify the exact thread form and sealing method; NPT, BSPP and BSPT connections require different mating arrangements.

Why use grade 316 stainless steel for this pneumatic fitting?

Grade 316 contains molybdenum, which improves resistance to some forms of localized corrosion compared with 304. It is often chosen on exposed food, beverage and pharmaceutical machinery where moisture and frequent cleaning are concerns. It is not immune to chloride pitting or crevice corrosion.

Can the FKM seals handle caustic washdown chemicals?

Not automatically. FKM resists many oils and industrial media, but strong or hot alkaline cleaners, steam and some sanitizers can damage certain grades of FKM. Verify the complete cleaning process, including chemical concentration, temperature and exposure time, for both the seal and the stainless body.

Is this fitting approved for direct food or pharmaceutical product contact?

No direct-contact or hygienic certification is established by this product listing. The fitting may be selected for pneumatic or vacuum circuits on processing machinery, but food-contact or sterile-process service needs separate confirmation of material compliance, surface finish, cleanability and manufacturer approvals.

How do I choose the correct tube and thread connection?

This model lists 12mm Tube, R3/8 Thread (BSPT). Verify the tube outside diameter and any stem or threaded port dimensions. NPT, BSPP, BSPT, M5 and 10-32 UNF are not automatically interchangeable. FOH is a secondary sourcing range alongside the standard S-series; compare the published specifications before substituting.
