Push-in fittings for pneumatic and lubrication service list at US$0.30–US$25 per piece across surveyed retail and wholesale channels, with engineered-metal variants from Festo and Parker concentrated in the US$6–US$25 band [S5][S6][S1].
Wholesale lots from Chinese manufacturers cluster in the US$1.00–US$20.00 range with 50-piece minimum order quantities, while brand-name polymer units sit at the US$0.30–US$2.00 end for the same tube diameters [S4][S1].
What a push-in fitting actually costs, by tier
Three price bands dominate the surveyed market, distinguished mainly by body material and pressure rating rather than by tube diameter alone [S4][S5].
Entry-tier polymer (POM/plastic collet, glass-filled nylon body, EPDM O-ring): US$0.30–US$1.20 per piece at 50-piece MOQ, common for 4–12 mm OD nylon or PU tubes in low-pressure shop-air service up to 8–10 bar [S4]. Mid-tier nickel-plated brass (BSP/BSPT thread, NBR seal, stainless grab ring): US$1.20–US$6.00 per piece, the working horse for general pneumatics at 10–16 bar [S1]. Engineered metal (316L stainless, FKM seal, full-metal grip, certified for aggressive media): US$6.00–US$25.00 retail, with Festo's NPQM metal push-in and Parker's Phastite permanent-compression range in this band [S5][S1].
Cost drivers engineers should weight first
Body material sets the largest single swing: a brass body carries roughly 3–5× the raw-material cost of an equivalent POM body, and a 316L stainless body roughly 6–10× again over brass, before machining is counted [S2][S5]. Pressure rating is the second lever: standard pneumatic push-in fittings are rated to 8–16 bar in surveyed datasheets, while lubrication-grade push-ins carry ratings to 80 bar with no special tooling, and hydraulic permanent-compression variants reach 1,550 bar (22,500 psi) [S3][S1].
Thread standard and seal type are quiet cost multipliers. BSP parallel with O-ring (Gas/ISO 228), BSPT taper with pre-applied PTFE, NPT dryseal, and Rc taper each require different machining, thread gauges, and seal components, and the wrong combination is the single most common leak path in field retrofits [S2].
Comparison: which type goes where

Four push-in styles appear across the surveyed catalogue, and the decision turns on media, pressure, and reusability rather than price alone. [S1]
Polymer push-in (POM, 4–12 mm OD, 8–10 bar): cheapest at US$0.30–US$1.20, suited to dry compressed air and inert gas in OEM machine builds; not for vacuum service above 0.5 bar absolute, and not reusable after high-cycle vibration [S1][S4]. Nickel-plated brass push-in (3–14 mm OD, 0.5–12 bar pneumatic, snap-in collet): the SAF RR series exemplifies this class, with BSP/BSPT threads, T/Y/90° configurations, and field-reusable design; priced roughly US$1.50–US$5.00 in catalogue channels [S2]. Metallic cost-effective push-in (Festo NPQM, all-metal release): priced US$6–US$15 retail, rated for metal-to-metal sealing in welding-cell and outdoor service where polymer collets would creep [S5]. Permanent compression push-in (Parker Phastite, 6–25 mm OD, up to 22,500 psi): the high-pressure end, where the "push" is followed by a mechanical swage; priced US$15–US$25+ and selected for hydraulic and high-pressure instrument service where the labour saving against welded or coned-and-threaded joints is the real value proposition [S1].
Total cost of ownership, not just piece price
Piece price is the smallest line on a five-year push-in spend sheet; the installation and rework line is not [S3].
A central-lubrication skid with 80 push-in connection points can be assembled in roughly 30% of the time required for equivalent compression fittings, and field-reusable push-ins allow point replacement without cutting the tube, dropping mean-time-to-repair on a 100-machine lubrication network from hours to minutes [S3]. Lubricant savings from a well-plumbed central system reach up to 40% versus manual greasing, an Opex line that dwarfs the Capex delta between a US$0.80 polymer fitting and a US$1.50 brass one [S3].

Standards, certifications, and the price impact

Three standard families touch push-in fitting cost directly, and the right one must be on the drawing before the RFQ goes out [S3][S2].
For plastic tubing paired with push-in fittings, DIN 73378 (PA6/PA12 HL grade) is the dominant European reference; Fritsche specifies 6×1 and 6×1.5 mm PA12 HL tubes at 89 bar working pressure, manufactured to CETOP dimensional criteria, and a push-in system outside that envelope is the fastest way to leak [S3]. For brass threaded bodies, ISO 228 (BSP parallel, G thread) and ISO 7 (BSPT taper, R/Rc threads) govern the seal surface, while ASME B1.20.1 covers NPT — mixing thread forms is the single most common cross-thread failure mode on imported fittings [S2]. For compressed-air service in machinery, ISO 14743 and the related CETOP RP 54P dimensional sheets define the tube-OD / stud-size matrix that keeps push-ins interchangeable across SMC/Festo/Parker/PNEUMAX catalogues [S1].
Where to buy, and the price spread that comes with it
DirectIndustry's aggregated catalogue lists 106 manufacturers and 516 product families for push-in and compression fittings, providing the broadest price-comparison surface in a single RFQ [S1].
European OEM channels (Festo, Parker, PNEUMAX, SAF) carry premium pricing, typically US$6–US$25 for engineered metal variants, with full traceability, lot certificates, and 3D CAD models, and lead times of 5–15 days within the EU [S1][S5]. Chinese wholesale via Made-in-China lists equal-diameter push-ins at US$1–US$20 with 50-piece MOQs and 15–45 day lead times, with FOB pricing on the major Ningbo and Shenzhen freight lanes [S4]. Surplus channels (eBay, industrial resellers) show used and overstocked Festo QS-G1/4-8 at roughly US$4–US$7 per piece in lots of six, a useful tier for non-critical maintenance stock [S6]. For site-level cost benchmarking on related gas-handling gear, the Precision filter price 2026: cost drivers, tiers, and selection logic breakdown and the Vacuum Generator Price and Cost Guide: 2026 Spend Map map apply the same material-pressure-volume logic to upstream and downstream components of the same pneumatic circuit.
Selection rule of thumb for 2026 sourcing

Specify the tube OD, the thread standard, the media compatibility, and the working pressure first, then match body material to environment: polymer for dry air at ≤10 bar inside enclosures, nickel-plated brass for general shop-floor pneumatics, 316L stainless for washdown, food, and outdoor, and full-metal permanent-compression for hydraulic and high-cycle vibration duty [S1][S2][S3][S5].
Track two live signals over the next sourcing cycle: brass and stainless surcharge deltas on the LME and SHFE (raw-material floor for tier 2 and tier 3), and container-freight indices on the Ningbo–Rotterdam lane, which still sets the China-to-EU landed-cost spread despite the 2024–2025 normalisation. Festo's NPQM metal push-in refresh and Parker's Phastite tooling extensions through 2026 are the OEM-side signals worth watching for pricing moves in the engineered-metal band [S5][S1].
