NITTO TYPE COUPLERS 1/4″ 3/8″ 1/2″ Male Coupler

Description

Technical Specifications (NITTO Hi‑Cupla Standard)

• Body Material: Chrome-plated steel (also available in brass or stainless steel upon request)

• Seal Material: NBR (nitrile rubber)

• Working Pressure: Typically around 1.0–1.5 MPa (≈145–218 PSI) depending on series

• Maximum Pressure: Around 2.0 MPa (≈285–290 PSI)

• Temperature Range: Generally from approximately –20 °C up to +80 °C; some variants support up to +180 °C using special seals such as FKM/EPDM

Hi‑Cupla Standard (20PM / 30PM / 40PM – Male Thread)

• Models by thread size:

  • 20PM – ¼″ BSP male

  • 30PM – ³⁄₈″ BSP male

  • 40PM – ½″ BSP male

• Equipped with automatic one-way shut-off, hardened wear-resistant components, and tested for durability (up to 100,000 cycles)

Hi‑Cupla 200 Series (20PM / 30PM / 40PM – Male)

• Similar dimensional offerings (¼″, ³⁄₈″, ½″ male BSP thread)

• Slightly lower working pressure around 1.0 MPa (≈145 PSI) with maximum pressure ≈1.5 MPa (≈215 PSI)

• Offers one-touch connection, improved flow rate, and free swiveling to avoid hose kinks

Stainless Steel Variants

In stainless steel (e.g., NS‑20PM, NS‑30PM, NS‑40PM):

• Working Pressure: ~1.5 MPa (≈218 PSI)

• Maximum Pressure: ~2.0 MPa (≈290 PSI)

• Temperature Range: –20 °C to +180 °C

• Designed with six locking balls, RoHS/REACH compliant, and tested to 100,000 cycles

Additional Highlights

• Flow Rate: For some models, about 35 SCFM at 100 PSI with 10 PSI pressure drop

• Interchangeability: Commonly compatible with other major quick‑coupler systems like RECTUS, CEJN, and similar Nitto variations
